Lip filler might be the most requested treatment in clinic, and also one of the easiest to get wrong, not because the procedure itself is complicated, but because so much of the decision-making happens before the needle ever goes in. Most of what goes wrong traces back to a handful of repeatable mistakes, the same ones, over and over, regardless of who’s doing the injecting.

So I wanted to write down the ones I actually see most, the stuff I’d tell a patient before their first appointment if I had five honest minutes with them.

Going in with a photo of someone else’s lips

Reference photos help, but lips don’t exist in isolation. The same amount of product can look completely different depending on your lip shape, your teeth, your bite, even the rest of your facial proportions. A good injector uses your photo as a starting conversation, not a copy-paste target.

Choosing the injector based on price alone

This is where a lot of the “migrated filler” or lumpy results I see actually start. Lips are thin, mobile, and vascular, technique matters more here than almost anywhere else on the face. The cheapest option isn’t automatically bad, but price shouldn’t be the deciding factor for an area this unforgiving of mistakes.

Assuming more filler = better results

Volume is only part of what makes lips look good. Shape, symmetry, and how the product moves with your natural expressions matter just as much. I’ve seen plenty of “overfilled” cases that technically didn’t use that much product, they just weren’t placed with shape in mind.

Not asking which product is being used

Not all lip fillers behave the same. Some are formulated specifically for flexibility and movement, others are firmer and better suited to structural areas elsewhere on the face. Using the wrong type in the lips is a common, avoidable reason results end up looking stiff or unnatural.

Getting filler right before a big event

Swelling is normal for the first few days, sometimes longer, and it doesn’t always go down evenly at first. If you have a wedding, a shoot, or any event where you want to look your best, that filler needs to happen weeks ahead of time, not days.

Skipping the follow up appointment.

Asymmetry and lumps are far more fixable early, before the product has fully settled. A lot of patients live with an uneven result simply because they never went back for the adjustment that was already included.

Not disclosing cold sore history

If you get cold sores, injections can occasionally trigger an outbreak. This is a simple thing to flag beforehand, and most providers can prescribe something preventive if you mention it.

Chasing bigger lips every few months

Lip filler migration doesn’t always happen because of one bad appointment. Sometimes it’s simply the result of repeatedly adding more product before reassessing what’s already there. Each new syringe on top of unresolved older filler makes it harder to predict where everything ends up sitting.

The injection itself only takes a few minutes. Getting the treatment plan right is what usually makes the difference between lips that simply look bigger and lips that actually suit the face !~

Every few months some new HIFU device shows up marketing itself as "the next Ultherapy, but better," and every single time patients ask me if they should switch. So let's actually talk about why Ultherapy's still holding its spot after all this time.

First, what actually makes it different. Ultherapy uses focused ultrasound to target deeper support layers, including the SMAS- evel area, which is one of the layers surgeons think about when lifting facial tissue. It's not just surface tightening, it's trying to create deeper support instead of only making the skin surface feel tighter, which is honestly a big reason it got FDA clearance as a "lift" and not just a tightening device.

The biggest thing for me though is the track record. Ultherapy's been around since 2009, and it's genuinely one of the most established and studied HIFU devices out there, with years of peer reviewed research, long term clinical use, and real time imaging that lets whoever's treating you actually see the layer before firing energy into it. Newer devices love to market themselves as faster or less painful or cheaper, and sometimes that's true, but newer doesn't automatically mean it's been studied nearly as much. A lot of newer devices have less long term public data, so I don't compare them as if the evidence is automatically equal.

That imaging piece actually matters more than people realize too. Ultherapy lets the provider see the tissue layer on screen before treating, which helps confirm they’re working at the intended depth instead of going too shallow or too deep. Some newer devices don’t have the same kind of real time imaging, so treatment depth can rely more on preset settings than confirmed anatomy specific to your face. For something working this deep, that visual confirmation isn't just a nice extra, it's a real difference in safety and precision.

That said, some newer devices do genuinely compete in certain ways, shorter treatment time, less discomfort, and for milder concerns that tradeoff can make sense. This isn't about newer options being scams, plenty are legit. It's more that "gold standard" here isn't just marketing fluff, it's reflecting how much research and imaging tech is actually backing it up compared to the alternatives.

Honestly what I'd tell someone deciding, if you're dealing with more noticeable sagging, jawline, under chin, brow, Ultherapy's precision and track record still make it the option I’d take seriously first. If your concern is milder and cost or comfort matters more to you, a newer device might be reasonable, just go in knowing you're probably working with less long term public data than what Ultherapy has behind it at this point.

Results build gradually over 2-3 months as collagen develops and usually last around a year, and yeah there's some discomfort during treatment since it's reaching that deep. but don't assume every "next-gen" HIFU has the same research depth, or that newer automatically means better for whatever you're actually trying to fix.

Gold standard doesn't mean it's the only option, it just means it's the one with the most evidence behind it after over a decade of real world use. Worth knowing what you're actually trading off if you decide to go with something newer instead.

One syringe doesn’t magically fit every face.

The internet loves giving one number as if everyone has the same skin, the same concerns, and the same goals. In reality, the right amount depends on how much skin you’re treating and how much coverage you’re aiming for.

A lot of people assume 2cc is enough for the whole face because that’s what they see online. In reality, 2cc is usually enough for a targeted area, not a full face treatment.

Here’s the general guide I use in clinic:

Cheeks only → Around 2cc

If your main concern is enlarged pores, acne scars, or rough skin texture on the cheeks, 2cc is usually enough to treat that area properly.

Cheeks + Chin → Around 3cc

Adding the chin helps improve overall skin quality and balance. This is a popular option for patients who don’t want to commit to a full-face treatment but want more than just the cheeks.

Full Face (light coverage) → Around 4cc

This gives a more sparing treatment across the entire face. Every area receives some product, but not as densely as a full rejuvenation protocol.

Full Face (good coverage) → Around 6cc

This is what I’d consider a proper full-face treatment. It allows enough product to cover the forehead, temples, cheeks, nose, under-eye area (when appropriate), chin, and jawline without stretching the product too thin.

One thing people don’t always realize is that Rejuran isn’t a filler. It isn’t there to add volume overnight. The goal is to improve skin quality by stimulating your skin’s own repair process over time.

Using too little product doesn’t make the treatment more natural, it often just means each area receives less than the amount needed to achieve meaningful results.

Of course, these numbers are only general recommendations. Every face is different. Someone with significant acne scarring or severe sun damage may need more product than someone simply looking to maintain healthy skin 🫡

Honestly I’d say most of my patients only apply sunscreen once, in the morning, and that’s it for the whole day. And then they’re surprised when spots show up anyway. So here’s the thing nobody really wants to hear: one application does not protect you all day!!

It just doesn’t hold up that long

Sunscreen isn’t some shield that stays up for 24 hours once it’s on. It breaks down from the UV itself, rubs off on clothes and pillows, gets diluted by sweat and oil, and physically thins out over a few hours. Some of the chemical filters actually degrade under UV exposure the more they’re doing their job, which sounds backwards but that’s part of why they need topping up. By hour 3 or 4 you’re getting way less protection than you think, even though nothing feels different on your skin, no burning, no obvious sign anything’s changed, which is exactly why people don’t realize it’s happening.

SPF 50 in the morning doesn’t mean SPF 50 all day

It means SPF 50 for about as long as the product’s still actually intact on your skin, which for most people is a lot shorter than a full day. Sweat, touching your face, wiping with a towel, even just talking and moving your face all day wears it down faster than people assume. By the time you’re heading home from work, whatever you put on that morning has likely broken down way more than you’d expect just from a normal day.

And yeah, being indoors doesn’t save you either

UVA goes straight through windows, glass barely blocks it at all. If you’re sitting near one for hours, working, driving, sitting by a window at a cafe, whatever, you’re still building up exposure the whole time, just without a sunburn to warn you it’s happening. This is actually a big reason why people get more sun damage on the side of their face and arm that faces the car window during long commutes, even without ever stepping outside.

So how often should you actually be reapplying

Every 2 hours if you’re outside or near windows for a while. Yes, even over makeup, there are spray and powder formulas made exactly for that, so “I don’t want to ruin my makeup” isn’t really a valid reason to skip it anymore. If you’re only doing SPF once in the morning, you’re basically unprotected for most of your day, and the pigmentation, fine lines, and sun damage you’re trying to avoid is still quietly happening the whole time, just slowly enough that you don’t notice it in the moment.

This stuff just adds up quietly over time

A lot of the spots and texture patients want fixed with laser or pico toning are honestly just years of missed reapplication catching up all at once. It’s rarely one bad day in the sun, it’s hundreds of ordinary days where protection quietly wore off by early afternoon and nobody noticed anything different until the damage had already built up underneath the surface.

If your skincare’s solid but you’re only applying SPF once a day, you’re not actually protected, you’re protected for a few hours and then quietly not for the rest of it.

HA skin boosters (like Juvelook’s HA line, or classic ones)

Most HA skin boosters use non cross linked or lightly cross-linked hyaluronic acid, allowing the product to spread through the skin and improve hydration rather than create structure like a traditional filler. Unlike fillers, the main difference isn’t necessarily the HA concentration, but the degree of cross-linking and the product’s rheological properties. Some skin boosters also combine different molecular weights of HA. Higher molecular weight HA mainly helps retain water and support hydration, while certain lower molecular weight fractions may have additional biological effects on skin remodeling, although this varies between formulations. Products like Juvederm Volite, Restylane Skinboosters Vital, and Belotero Revive all fall under the HA skin booster category, but they differ in their HA formulation, cross-linking, and intended clinical use.

Rejuran (PDRN)

Rejuran is different because its active ingredient is polynucleotide (PN) purified from salmon DNA, rather than hyaluronic acid. Instead of mainly improving hydration, PN is thought to support tissue repair by modulating cellular signaling pathways, including activation of adenosine A2A receptors. Experimental studies suggest this may promote fibroblast activity, collagen remodeling, and increased expression of factors involved in wound healing, such as VEGF. That is why Rejuran behaves very differently from an HA skin booster. The goal is improving skin quality and regeneration over time, rather than simply adding water to the skin.

Why this matters practically

If someone wants immediate glow before an event, HA boosters make more sense, fast, visible, predictable timeline.

If someone’s dealing with acne scarring, textural damage, or general skin quality decline over time, Rejuran makes more sense because it’s actually addressing tissue repair, not just hydration.

People often expect Rejuran to give that instant plump the way HA does, and get disappointed at the one week mark when nothing’s really changed yet, when actually the real change is still happening under the surface and shows up more around 4-6 weeks.

Because Rejuran works through a regenerative mechanism instead of a filling one, it’s usually done in a series (2-3 sessions spaced a few weeks apart) rather than as a one off, whereas HA boosters can genuinely be a single session and still show a visible result. Mixing up which one you’re booking based on price alone is how people end up disappointed, they’re not competing versions of the same thing, they’re solving different problems entirely.

Had a patient last week who’d switched her entire routine three times in two months trying to fix her breakouts, and the actual culprit turned out to be her new pillowcase. Not even kidding. So here’s a few things I bring up constantly that have nothing to do with what’s in your skincare products

Your phone screen

I know people joke about this one, but it's real. You're pressing a screen covered with oil, bacteria, makeup, and whatever else you've touched that day against your face over and over again.

If you keep breaking out on the same cheek or along your jawline where you hold your phone, I'd definitely think about cleaning it more often.

Pillowcases

Cotton pillowcases hold onto oil, product residue, and dead skin, and most people go way longer than they should between washes. If you’re breaking out mostly on one side of your face, or around your temples and forehead, check when you last changed it before blaming your moisturizer.

Hormonal cycles

Obviously, but people underestimate how much. A lot of patients will change three products in a row trying to fix breakouts that are just showing up the same week every month around their cycle. If it’s clustering around the jawline and chin and it’s cyclical, that’s more likely hormones than anything topical.

Hair products

Conditioner, dry shampoo, styling products, they run down onto your forehead and along your hairline constantly, and people never think to connect breakouts there to what they’re putting in their hair. This one gets missed a lot.

Stress

People know stress can make acne worse, but they don't always realize there's actual biology behind it. Higher cortisol can increase oil production and inflammation, so yes, stressful weeks really can show up on your face.

Diet, but not in the way TikTok says

It’s not really cut out sugar and dairy and you’ll be clear,  that’s an oversimplification that gets thrown around a lot without much nuance. For some people there’s a real connection, usually tied to blood sugar spikes, but it’s individual, not universal, and I get frustrated seeing it presented as a blanket rule.

Touching your face in general, which people do way more than they realize throughout the day without noticing.

Certain medications

Birth control changes, some supplements, even starting or stopping certain meds can trigger breakouts that have nothing to do with your face routine at all.

And honestly, sometimes it’s just your gut. Digestive issues can absolutely show up on skin, this one’s harder to self diagnose but it’s real and worth mentioning if nothing else adds up.

The point isn’t that skincare doesn’t matter, obviously it does. But I see so many ppl cycling through product after product convinced the answer is out there in some serum, when the actual trigger is a pillowcase they haven’t washed in a month or a stress spike from work..

In clinic, I usually separate under eye concerns into a few main types. Some patients have hollowness, where the tear trough is sunken and casts a shadow. Others have pigmentation, where the skin itself is simply darker than the surrounding area. Some have thin skin with visible vessels, giving the area a bluish or purple tint. Others deal with puffiness or bags, caused by fat or fluid creating a bulge. And some have fine lines or loose skin, which gives the under eye a crepey, worn out appearance.

So before jumping into any treatment, the first step is figuring out which of these is actually driving that tired look.

1/ If the main issue is hollowness

This is usually the hardest one to treat without injections. True under eye hollowness is often a volume or anatomy issue, so creams, lasers, and lifting devices can improve the skin quality around it, but they usually cannot fill the hollow completely.

For this, clinics may discuss tear trough filler, usually a softer HA like Belotero or Restylane’s eye specific line, around 0.5-1ml per side, with results visible immediately and lasting 9-12 months. Collagen stimulators like Sculptra are a slower option, typically 2-3 sessions spaced 4-6 weeks apart, with results building over 2-3 months but lasting longer, closer to 12-18 months. Under eye filler is also one of the treatments where technique matters a lot, because the area is thin and unforgiving. If the hollowness is more severe, from bone loss or significant fat atrophy, fat grafting or surgery becomes the more realistic conversation.

2/ If the main issue is dark color

If the darkness is brown pigmentation, pico laser (like PicoSure) is usually the go to, typically 3-4 sessions spaced 3-4 weeks apart with minimal to no downtime, paired with topical tranexamic acid or vitamin C and daily sunscreen to keep it from relapsing.

If the color is more blue or purple, it may be from thin skin or blood vessels showing through. In that case, pigment lasers may not do much. Vascular lasers like Vbeam can help if visible vessels are the actual cause, but results tend to be more modest and very case dependent, so the plan has to be different and I try not to overpromise here.

This is why some people do many dark circle treatments and feel like nothing changes, because the cause was not pigment in the first place.

3/ If the main issue is fine lines or thin skin

For fine lines and crepey texture, I’d think more about collagen support. This can include microneedling RF (Morpheus8), or skin boosters like Profhilo or Rejuran, usually 2-3 sessions about 4 weeks apart with a day or two of mild swelling.

But under eye skin is thin, so I don’t like being too aggressive here. Too much heat or too much energy in the wrong patient can make the area look more hollow or tired.

4/ If the main issue is puffiness or eye bags

This is different from hollowness. If the under eye looks puffy because of fat pads or fluid retention, filler may actually make it look worse.

For mild cases, lifestyle, swelling control, lymphatic care, and sometimes energy based tightening can help a little. But if the eye bag is structural, lower blepharoplasty or fat repositioning may be the more realistic option.

I also got a question about low downtime options for under eye hollowness without under eye injections, so let’s talk about that.

Yes, there are low downtime options, but I’d be honest about the limit. If it is true hollowness, non injection treatments usually improve the skin around the hollow, but they don’t replace lost volume.

For low downtime, I’d consider things like RF eye lifting, eye focused tightening treatments, or mild laser treatments if there is pigmentation or texture, usually a few sessions apart with little to no downtime. These can help the area look smoother, tighter, and less tired. But if the hollow is deep because of bone structure, fat loss, or a strong tear trough shadow, non injection treatments may only give a subtle improvement.

Also, if you don’t want injections directly under the eyes, sometimes the doctor may look at the mid cheek support instead. In some faces, improving cheek support can soften the under eye shadow without injecting directly into the tear trough. But this still depends on your anatomy and should be done very carefully.

So my answer would be: yes, low downtime non injection treatments can help mild under eye tiredness, texture, and skin quality, but they may not fully correct true hollowness.

Thanks to u/aquinmac20 for suggesting this topic. I’m glad I can talk about this because Korean lifting machines can get confusing really fast.

Some patients need overall elasticity and skin firmness. Some need more careful work around smaller areas like the eyes or mouth. And some are more concerned about lower face heaviness, jawline softness, or early jowling.

That’s why skin thickness, facial fat, sagging pattern, hollow areas, and pain tolerance matter a lot.

First, Oligio X

Oligio X is more of an upgraded RF tightening treatment.

The main focus is collagen stimulation, skin elasticity, texture, pores, fine lines, and mild lifting. It has G mode and X mode, so the treatment can be adjusted depending on the area and skin condition.

I’d usually think of Oligio X for someone who feels like their skin is becoming less firm, their jawline is starting to soften a little, or their overall elasticity is not like before.

It’s not a facelift, of course. But for early sagging and maintenance, it can be a good option.

Next, Oligio Kiss

Oligio Kiss feels more like a detailed and customized approach.

A lot of clinics use it for smaller or more delicate areas, like around the eyes, around the mouth, curved areas, or areas where you don’t want to be too aggressive.

Depending on the clinic’s protocol, it may involve RF, HIFU, or a combination of both. So it can be useful when someone needs both skin elasticity improvement and some deeper lifting support, but in a more controlled way.

I’d think of Oligio Kiss for people with fine lines around the eyes or mouth, thinner skin with early sagging, or people who want a gentler and more detailed lifting plan.

Not everyone needs strong energy everywhere. Sometimes the result is better when the treatment is adjusted carefully by area.

Then, Xerf

Xerf is also RF based, but I think of it more for deeper tightening and lower face contour support.

If someone says their lower face feels heavier, their jawline is not as sharp, or they’re starting to see mild jowling, I’d compare Xerf more seriously.

It’s still non surgical, but compared to lighter RF treatments, Xerf feels more focused on face line, lower face tightening, and jawline definition.

About the RF question: is Oligio Kiss RF the same as Oligio X RF?

I wouldn’t say they are automatically the same.

Even if both involve RF, the result is not decided by the machine name only. It depends on the mode, tip, contact area, cooling, energy setting, depth, skin thickness, fat layer, and which part of the face is being treated.

Oligio X is more straightforward when the goal is overall RF tightening and elasticity. Oligio Kiss is usually more customized, especially when treating smaller areas or when RF and HIFU are being combined.

So if someone asks me whether Oligio Kiss RF is exactly equivalent to Oligio X RF, my answer would be no, I wouldn’t assume that unless the clinic clearly explains the actual protocol.

And yes, if RF and HIFU are separate modes or tips, the doctor may be able to focus more on RF and reduce or skip HIFU depending on your face. This is especially important for people with thinner faces, hollow areas, or not much facial fat, because more deep energy is not always better.

Hope this helps clear things up. If there are any other treatments or clinic-related topics you guys want me to talk about next, leave it in the comments. I’ll try to make a proper post when I have time ☺️

Thank you u/aquinmac20 for recommending this topic. I’m glad I can bring some helpful information here because Korean lifting machines can get confusing very fast.

These machines are often grouped together because they all sit in the lifting and tightening category, but they don’t target the face in the exact same way.

Some are better for overall elasticity and skin texture. Some are more useful for smaller, delicate areas. And some are chosen more for jawline or lower face contour. That’s why the treatment plan can change a lot depending on skin thickness, fat amount, sagging pattern, hollow areas, and pain tolerance.

1/ Oligio X

Oligio X is more like an upgraded RF tightening treatment.

The main point is collagen stimulation, elasticity, texture, pores, fine lines, and mild lifting. It also has G mode and X mode, with different tips, so the energy can be adjusted more depending on the area.

I’d think of Oligio X for someone who says their skin feels less firm, their jawline is getting a little soft, or their overall elasticity is not like before.

It’s not a facelift, but for early sagging and maintenance, I think it makes sense.

2/ Oligio Kiss

Oligio Kiss feels more like a detailed and customized approach.

A lot of clinics use it for smaller or more delicate areas, like around the eyes, around the mouth, curved areas, or areas where you don’t want to be too aggressive.

Some clinics also use it as a treatment that combines RF and HIFU, so it can help with both skin elasticity and some deeper lifting support.

I’d think of Oligio Kiss for people who have fine lines around the eyes or mouth, thin skin with early sagging, or people who want a more gentle and detailed lifting plan.

Not everyone needs strong energy everywhere. Sometimes a softer and more customized approach is better.

3./XERF

XERF is also RF based, but I think of it more as deeper tightening and contour support.

If someone says their lower face feels heavier, their jawline is less sharp, or they’re starting to see mild jowling, I’d probably compare XERF seriously.

It’s still not surgery, but it feels more focused on face line and lower face contour compared to lighter RF treatments.

Replying to the RF question about Oligio X vs Oligio Kiss

About whether the RF from Oligio Kiss is the same as Oligio X, I wouldn’t automatically assume they are equivalent. Oligio X publicly emphasizes stronger RF output, dual mode, optimized tips, and upgraded cooling. With Oligio Kiss, if the clinic or company does not clearly disclose the RF power and specs, I would be careful saying it is the same RF.

RF is not only about the machine name. It depends on power, tip size, contact area, cooling, pulse pattern, depth, and settings.

So my answer would be: RF from Oligio Kiss may still work well, but I would not call it the same as Oligio X unless the clinic can clearly explain the specs and protocol. And yes, if RF and HIFU are separate tips or modes, the doctor may be able to use more RF and skip or reduce HIFU depending on your skin.

Also, if there’s any treatment or clinic related topic you guys want me to talk about next, leave it in the comments. I’ll try to make a proper post about it when I have time ☺️

I actually like talking about lip filler because people think it is such a small, simple treatment, but lips are one of the easiest areas to make look unnatural.

A good lip filler result is not just about making the lips bigger. It is about balance. The lips sit right in the center of the face, so even a small change can make the whole face look softer, prettier, or sometimes awkward.

1. Too much volume from the beginning

This is probably the most common reason lip filler looks unnatural.

I know a lot of patients come in with a photo and want that full lip look immediately. But lips are not like cheeks or temples where volume can be hidden more easily. If you overfill the lips in one session, they can start pushing forward instead of looking naturally plump.

This is how people end up with that duck-lip look, or lips that feel too heavy for the rest of the face.

For lips, I really prefer building slowly. A small amount first, let it settle, then adjust if needed. It may feel slower, but this is usually how you get lips that look like they actually belong to your face.

2. Old filler that has already built up

Another big reason is old filler.

A lot of people forget that lip filler does not always disappear perfectly. If someone has done filler many times, especially at different clinics with different products, the lips can become stiff, uneven, or bumpy.

Sometimes the shape is already set in a bad way, so adding more filler only makes the problem worse.

In those cases, the prettiest result usually comes from dissolving first and redesigning from zero. I know patients hate hearing this because they don’t want to lose volume, but if the base shape is already distorted, more filler is not going to fix it.

3. Copying a lip shape that does not suit your face

This is also very common. Patients bring celebrity photos or influencer photos and want the same shape. But lips depend so much on your nose, chin, teeth, facial length, and side profile.

A lip shape that looks amazing on one person can look too projected, too flat, or too childish on another face.

Especially from the side, the E line matters a lot. If the lips are already forward compared to the nose and chin, adding too much volume can make the profile look protruded. If the chin is weak, the lips can look even more pushed out after filler.

One more thing people forget: movement

Some lips are uneven because of movement, not volume.

One side may pull higher when smiling, the corners may move differently, or the lower lip may fold in a way that makes the mouth look sad or crooked.

If the problem is muscle movement, filler alone will not fully correct it. In some cases, a tiny amount of Botox around the mouth area can help relax the pull and make the lip line look more stable. But this has to be done carefully because too much Botox around the mouth can affect your smile or speech.

I get this question a lot from younger patients, especially in Korea where skin clinics are so common.

A lot of people in their 20s come in asking if they should already be doing Botox, lifting, lasers, skin boosters, or some kind of prevention treatment. And honestly, my answer is usually: not necessarily.

Most people in their 20s don’t need cosmetic treatments for aging yet. The skin still has good collagen, good elasticity, and usually recovers faster than older skin. So when someone in their 20s says their skin suddenly looks bad, I’m usually not thinking “aging” first.

I’m thinking acne, clogged pores, acne marks, dehydration, sun damage, irritation, or damaged skin barrier.

So for this age group, I don’t really like the idea of doing treatments just because they’re trendy. The focus should be more on keeping the skin healthy and treating actual problems early.

For example, acne is one thing I wouldn’t ignore. If someone has active acne or early acne scars, treating it early can save a lot of trouble later. Acne scars are much harder to improve once they become deeper, so in that case, treatments like acne laser, gentle peels, LED, calming treatments, or light microneedling can make sense.

Pigmentation is another common one. A lot of younger patients think pigmentation is only an older skin problem, but acne marks, sun exposure, picking at the skin, or hormones can cause it quite early. For this, gentle laser toning, pico laser, or brightening care can help, but I would be careful with going too strong. If the skin is sensitive or prone to PIH/melasma, aggressive treatments can make things worse.

And honestly, sunscreen is still the boring answer that matters the most. If you’re doing pigment treatments but not using sunscreen properly, you’re making the treatment work twice as hard.

Another thing I see a lot in people in their 20s is damaged barrier. The skin looks dull, red, oily but dry, and easily irritated. Usually it’s from too many actives, over-exfoliating, strong retinol too early, poor sleep, stress, alcohol, or just changing products too often.

In that case, I would not jump straight into lasers. If basic moisturizer stings, that’s usually a sign the skin needs repair, not more procedures.

For Botox, I don’t think everyone in their 20s needs it. It can be useful if someone has very strong expression muscles and the lines are already staying even when the face is relaxed. But if there are no visible lines yet, I wouldn’t rush. If we do it, I prefer a very light dose. The goal is prevention and soft movement, not a frozen face.

Fillers are where I’m more cautious. Most people in their 20s don’t need fillers for aging. Sometimes filler is used for balance, like lips, chin, or small contour correction, but I don’t like heavy filling at a young age. Too much cheek filler, under eye filler, or trendy facial sculpting can look strange over time. Trends change, and filler doesn’t always disappear as quickly as people think.

For lifting treatments like HIFU, Thermage, Ultherapy, or RF, I also don’t think they’re necessary for most people in their 20s. If there is no real laxity, there’s not much to lift. And if the face is already slim or hollow, too much heat-based treatment can sometimes make the face look more tired.

Skin boosters are probably one of the safer maintenance type treatments when used properly. They can help if the skin is dehydrated, dull, or rough. But even then, I wouldn’t call them essential. They work best when your basic skincare is already stable.

So my general advice for people in their 20s is pretty simple: don’t treat aging if aging is not the problem.

Treat acne early. Don’t wait too long with scars. Be gentle with pigmentation. Fix the skin barrier before doing strong treatments. Use sunscreen every day. Don’t overfill the face. And don’t do lifting treatments just because someone says it’s preventative.

There’s nothing wrong with doing skin treatments in your 20s, but they should have a reason.

A lot of people in their 40s come to Korea thinking they need one anti aging treatment to fix everything. But honestly, 40s skin is usually not just one problem.

It is usually a mix of volume loss, mild sagging, thinner skin, pigmentation, bigger looking pores, and slower skin recovery. So if you only treat one thing, the result can feel disappointing.

For most people, I would divide treatments into a few categories.

1. Botox (good, but don’t overdo it)

Botox is useful for forehead lines, frown lines, crow’s feet, jaw clenching, and sometimes neck bands. In the 40s, I usually prefer softer Botox rather than freezing everything.

Too much Botox can make the face look stiff, especially if the lower face is already starting to lose support. The goal should be to relax strong movement, not remove all expression.

2. Filler (only where volume was actually lost)

Filler can be very helpful in the 40s, but it needs to be used carefully.

The areas that often benefit are the temples, midface, cheeks, and sometimes the nasolabial area. But putting filler directly into every fold is not always the answer. Sometimes the fold is there because the upper face has lost support.

Good filler should make the face look more rested, not puffy. In Korea, many clinics are conservative with filler compared to the “overfilled” look people worry about, but you still need to choose the injector carefully.

3. Collagen stimulators

This is one category I think makes a lot of sense for people in their 40s.

Treatments like Sculptra, Juvelook Volume, PDLLA, PLA, or similar collagen stimulating injectables are not instant like filler. They work gradually by encouraging collagen production.

They are better for people who want slow improvement in firmness, skin quality, and mild volume loss. The downside is that results take time and you usually need a series. Also, technique matters a lot. These should not be injected casually.

4. Skin tightening devices

Ultherapy, HIFU, Thermage, RF lifting, and similar devices can help with mild to moderate laxity.

They are not the same as a facelift. I think this is where people get disappointed. These treatments can give subtle tightening, especially around the jawline, lower face, brows, and neck, but they will not dramatically lift heavy sagging.

For someone in their 40s with early laxity, these can be useful as maintenance. For someone with significant skin laxity, threads or surgery may be more realistic.

5. Lasers (choose based on pigment, texture, or pores)

Lasers are huge in Korea, but laser is too general. There are many types.

For pigmentation, clinics may use pico lasers, Q switched lasers, toning lasers, or 1927 nm/thulium-type lasers.

For pores, texture, acne scars, and fine lines, fractional lasers or fractional RF may be better.

For redness and broken capillaries, vascular lasers are more appropriate.

The important thing is not to chase the strongest laser. Especially in your 40s, aggressive heat can sometimes worsen pigmentation or damage the barrier if your skin is not prepared.

6. Skin boosters

Skin boosters are very popular in Korea for a reason. They don’t lift like filler and they don’t erase wrinkles like Botox, but they can improve hydration, glow, elasticity, and overall skin texture.

Common categories include HA boosters, PN/PDRN-type treatments, amino acid blends, and other microinjection formulas.

I usually see them as “skin quality” treatments. They are nice when the skin looks dull, thin, dry, or tired. But they are not enough if the main issue is sagging or deep volume loss.

7. Threads

Thread lifts can help with mild jowling or midface sagging, but they are not magic.

They work best when the skin is not too heavy and the sagging is not too advanced. In some people, threads give a nice subtle lift. In others, the result is underwhelming or temporary.

I would not start with threads automatically. I would first look at whether the issue is volume loss, skin laxity, or true tissue descent.

8. Pigmentation

Pigment in the 40s can be tricky because you may be dealing with sun spots, melasma, post-inflammatory pigmentation, redness, or a mix of all of them.

This is why one random laser session often does not solve everything.

For pigment, I would be careful with heat, especially if you are melasma-prone or have Asian skin. Gentle repeated treatments plus sunscreen and good topical skincare usually work better than one aggressive session.

My personal approach would be: don’t do everything at once. Start with the main aging issue, then build from there. For example, Botox for movement lines, filler or collagen stimulators for support, RF or HIFU for laxity, lasers for pigment or texture, and skin boosters for glow.

The biggest things I’d be careful about are overfilling the face, overheating the skin with too many devices, and damaging the skin barrier. In your 40s, the best result is usually not dramatic. It should just make you look fresher, firmer, healthier, and more rested.

Having a sharp, snatched jawline is a massive beauty standard here in Seoul. But I see so many patients coming into the clinic super frustrated because their double chin just won't budge, no matter how much weight they lose.

They usually want to book "whatever works fastest," but there is a massive trap here. Treating the under chin area depends entirely on one question: Is your double chin caused by actual fat, or is it just sagging skin?

If you pick the wrong treatment, you are basically throwing your money away. Let's break down the two most popular options in Korea right now and how to choose.

Fat-Dissolving Injections: For actual fat volume. We use deoxycholic acid based formulas (like V-Olet) or customized clinic lipo-slim cocktails. The solution physically breaks down and destroys the fat cells, and your body metabolizes them over a few weeks.

Best for: A soft, pinchable, full under chin profile where you actually need slimming.

It does not lift or tighten skin. Expect a few days of looking like a bullfrog from the swelling before the magic happens.

HIFU Lifting (Shurink / Ultherapy): For loose, sagging skin. These machines use focused ultrasound energy to hit the deep SMAS muscle layer under your chin, causing it to contract and tighten. It's like a non-surgical shrink-wrap for your jawline.

Best for: Loose skin, early jowl sagging, or structural heaviness where there isn't actually a lot of fat to pinch. One session a year and you're set.

But it does not dissolve fat.

To be completely honest, most patients who come into my clinic actually have a little bit of both, some fat volume and some skin laxity.

If you just dissolve the fat, you are left with loose, deflated skin hanging under your chin. If you just do HIFU, the ultrasound waves can't fully get through a thick layer of fat to lift the muscle effectively.

That is why the gold standard in Seoul is combining them in the same season. We use the injections to melt away the fat pocket, and then we blast the area with Shurink Universe or Ultherapy to tightly snap the skin back against the jawbone. That is how you get that razor sharp profile.

If you are looking at your profile in the mirror and can't tell if you need melting or lifting, leave a comment below. I'll check back when I cann😉🙌🏻

So let’s talk about the absolute hardest thing to treat in dermatology: Acne Scars.

I always have to be brutally honest: if you have deep, indented acne scars (ice pick, boxcar, or rolling scars), just paying for a basic laser package is going to be a waste of your money. Lasers like Fraxel, Pico Fraxel, or Secret RF are amazing for smoothing the skin surface, reducing pores, and fixing post-acne redness. But they cannot lift a deep dent on their own.

The reason your skin looks pitted is because the scar is physically being pulled down by tough, fibrous bands underneath the skin. If you don't cut those bands or fill the hole, no amount of top layer laser will make your skin flat.

1. Subcision & TCA Cross

If you have rolling scars (the ones that look like gentle waves), we have to do subcision. We literally take a tiny needle or cannula under the skin and physically cut the fibrous bands that are pulling the scar down.

If you have those deep, sharp ice pick scars or enlarged pores, we use TCA Cross. We drop a tiny amount of strong acid exactly into the hole. It purposely damages the scar to force the skin to scab and rebuild itself upwards.

A warning for Asian/melanin rich skin: TCA Cross is incredible, but if a doctor uses an acid concentration that is way too high to try and rush the results, you will get severe post inflammatory hyperpigmentation (PIH) that takes months to fade.

2. Rejuran S vs Juvelook

Once we cut the bands with subcision, there is now an empty pocket under the scar. If we just leave it alone, the body sometimes heals right back down into a dent again. We need to fill it so the skin stays lifted. In the past, clinics used regular HA fillers, but they don't last and can look unnatural.

Now, the two biggest heroes for acne scars in Korea are Rejuran S and Juvelook.

• Rejuran S: This is the Scar version of Rejuran. It is much thicker than the normal black box Rejuran Healer. Because it is highly concentrated salmon DNA, it is the ultimate healer. If your scars are still very red, inflamed, and your skin barrier is completely destroyed from aggressive acne breakouts, Rejuran S is incredible for repairing the damaged tissue.
• Juvelook: This is the current gold standard in Seoul for indented, pitted scars. Juvelook is a collagen stimulator (PDLLA). When we inject it directly under the acne scar, it creates a microscopic scaffold. Over the next 4 to 8 weeks, it forces your body to build brand new collagen right inside that dent. It literally fills the hole from the inside out using your own tissue, and the structural results last 1 to 2 years.

Acne scars require patience. You cannot completely erase them in a 5 day tourist trip to Seoul. Usually, it takes a minimum of 3 to 5 sessions of a customized cocktail: Subcision to release the scar + Juvelook pumped under it to build volume + a surface laser to blend the edges.

I actually love talking about this because everyone knows Thermage, but Korean machines like Oligio X and XERF are getting so good now and they are huge in Seoul right now.

Let's talk about the pain because some mentioned they are pretty painless.

To be totally honest as a doctor, nothing that actually delivers enough heat to build long lasting collagen is 100% painless. If it doesn't hurt at all, it's probably not working. But compared to Thermage (which can be a nightmare for some people), yes, Oligio X and Xerf are a breeze.

Oligio X has an amazing upgraded cooling gas system compared to the original Oligio, so it feels mostly like warmth with a few hot snaps. Xerf also has continuous real time cooling. With Xerf, because it goes deeper, you might feel a deep sudden heat or a quick zing especially near your jaw bone where there is less fat. But it's very tolerable. We usually just use numbing cream for both and my patients sit through it perfectly fine without needing sleep anesthesia.

Now, which one has better and long lasting results?

Here is the main scientific difference you need to know:

Oligio X is a single frequency (6.78 MHz) monopolar RF. This wavelength targets your dermis. So it is fantastic for skin elasticity, smoothing out fine lines, and giving you that tight, bouncy skin surface.

Xerf is a newer technology because it uses DUAL frequencies (6.78 MHz + 2 MHz). This is the game changer. The 6.78 MHz tightens the surface just like Oligio, but the 2 MHz wavelength penetrates much deeper into the tissue, hitting the retaining ligaments and deeper fat layers.

Because Xerf works on the deep structural layers AND the surface at the same time, the lifting effect is generally more noticeable and lasts longer. Oligio X is more for tightening the skin envelope, while Xerf actually gives you a bit of structural lifting and contouring, especially around the lower face and jawline.

So which one would I recommend based on efficacy and cost?

It really comes down to your face shape, age, and budget!

• If you are in your 20s or 30s, your face is already pretty structured, you don't have much sagging, and you just want preventative care, tighter skin, and better elasticity: go with Oligio X. It is usually more affordable than Xerf, and it does exactly what you need for a great price point.
• If you have some lower face sagging, a little bit of a double chin, or you are noticing your jawline isn't as sharp as it used to be: I highly recommend paying a bit more for Xerf. Because it hits those deeper ligaments, it will give you that contouring and lifting effect that Oligio X might not fully achieve.

Also, just a tip: because Xerf is the shiny new toy in Korean clinics, the cost will be higher right now. But if you have the budget and want something that bridges the gap between Thermage (which is great for surface) and Ultherapy (which is great for deep lifting), Xerf is an amazing hybrid choice.

Let me know if you have any other questions. I always tell my patients that the machine is important, but having a doctor who knows how to control the energy and shoot the right vectors for your specific face shape is even more important!

A lot of people panic after Rejuran because right after the treatment, the face can look… honestly a little scary.

You expect glowing skin, but instead you see small bumps everywhere like mosquito bites.

Rejuran is injected very superficially into the skin. It is not placed deep like filler. So right after injection, you can literally see small raised bumps where the product was placed. This is usually just the product and swelling sitting inside the skin before it slowly spreads and calms down.

In most cases, these bumps go down within a few hours to 1–2 days.

But of course, not everyone heals the same. If your skin is very thin, sensitive, or if you did Rejuran around the under eyes, the bumps can look more obvious. Under eye skin is so thin that even a tiny bit of swelling can look dramatic there.

Usually, I would not worry too much if the bumps are small, soft, similar size, and slowly getting flatter.

A bit of redness, tiny injection marks, mild swelling, or small bruises can also happen. It does not mean the treatment failed or the clinic injected it wrong.

What I would pay more attention to is when one area becomes more painful, more red, warm to touch, or keeps getting bigger instead of calming down.

That is different.

Also, if there is one hard lump that stays for a long time and does not change, that is not the same as normal Rejuran swelling. Normal bumps should gradually soften and flatten. They should not stay firm for weeks.

I think the confusing part is people call everything a bump. The small mosquito bite bumps right after treatment are usually normal.

A bruise can also feel a little raised. Irritation can look red and angry.

But a true nodule is more persistent. It does not calm down day by day like normal swelling.

So I usually tell people to look at the direction, not just the bump itself.

Is it getting better every day? Probably normal.

Is it getting more painful, more swollen, more red, or staying hard in one spot? Then you should ask the clinic to check.

Also please don’t massage it aggressively unless your clinic specifically told you to. I know it is tempting because you want the bumps to disappear faster, but rubbing too much can make the skin more irritated, especially right after injection.

Same with sauna, alcohol, intense workout, and strong skincare. These can all make the redness and swelling look worse.

So my honest answer is, Rejuran bumps are usually not something to panic about. They are expected because of how shallow the injection is. But they should calm down, not get angrier.

cellREDM is EVERYWHERE in Korea recently 🧐 patients keep asking me if it is the new Rejuran or if it replaces RE20.

To me, both treatments are in that regenerative/repair type category. So these are not filler type treatments and not really those glass skin overnight treatments either. They are more treatments that slowly improve the skin condition itself over time.

RE20 feels more like a skin recovery/repair treatment. Those with damaged skin barrier, redness, irritation after lasers, thinner skin or acne inflammation usually respond pretty nicely to it.

Usually with RE20, the skin just starts looking calmer, less irritated and healthier overall. Makeup also tends to sit better once the inflammation settles down.

I also feel like RE20 works better for patients whose skin is constantly sensitized from too many lasers, over exfoliation, strong skincare or acne treatments. In Korea I see this A LOT actually!

The texture improvement with RE20 is usually softer and more natural looking. Not really that super shiny glass skin finish social media likes.

Meanwhile cellREDM feels more focused toward collagen regeneration and overall rejuvenation. Most patients asking for cellREDM are usually concerned about pores, elasticity, dull skin, fine lines and early aging.

Compared to RE20, I feel like cellREDM gives more of that skin quality upgrade feeling over time. Patients usually say their skin feels firmer, smoother and more refreshed rather than just calmer.

I also noticed patients who already like treatments like Juvelook, Rejuran or exosomes are usually interested in cellREDM too because the treatment goals overlap quite a bit.

But personally I do not really see cellREDM as a replacement for RE20 because the patient types are a bit different.

If someone has very sensitive skin, compromised barrier, post laser redness or active inflammation, I would probably still lean more toward RE20 first before trying stronger regenerative treatments. But if the patient mainly wants smoother texture, elasticity and more overall rejuvenation, then cellREDM makes more sense to me.

Another important thing is expectations! With treatments like RE20, cellREDM, Rejuran,.. the results are usually more gradual and cumulative.

Pain wise, I feel like cellREDM is easier than original Rejuran for most patients. Downtime also depends a lott on the injection technique and injector type. Even with very good products, if the injection is too superficial or aggressive, patients can still end up swollen or bruised for days.

One thing I noticed is that regenerative treatments evolve very quickly. Every year there is always a new ingredient, new protocol, new combination treatment, new skin booster trend.

But at the end, I still think understanding the patient's actual skin condition is more important than just choosing whichever treatment is trending at the moment.

If you’re here for like 5 days and still wanna go outside, eat, shop, take photos etc, there are some treatments that make way more sense than others bc some of the treatments I see tourists booking are actually insane 🥴 like subcision, aggressive lasers, rejuran or filler all before their flight home

Then they spend the whole trip swollen!!

One thing I actually recommend a lot is skin botox (dermotoxin)

Not regular botox btw, it’s injected very superficially into the skin instead of the muscles

So it doesn’t really freeze your face, it’s more for oil control, smoother texture, pores looking a bit tighter, makeup sitting better

Usually the skin starts looking nicer after like 1-2 weeks
Downtime is pretty low too except tiny bumps for few hours depending on skin thickness

Another thing korean clinics use on literally everyone is LDM

I feel like tourists never know what this machine is because it sounds underwhelming compared to all the flashy lifting lasers but honestly for irritated skin, dry skin, redness, damaged barrier, post laser inflammation… it works really nicely

It uses ultrasound frequencies that switch really fast, so instead of damaging the skin it’s more calming /repairing

I use it a lot after stronger procedures because it helps calm down the heat and irritation faster. Also if someone overdid tretinoin before coming to Korea… LDM usually saves them

For jawline / lower face I think Onda is becoming really popular lately

Especially for people who don’t necessarily need lifting but have slight heaviness around the lower cheek or double chin

It targets fat + tightening together so the face looks a bit cleaner over time, not immediate though
Usually looks better after few weeks once swelling goes down and the lymphatic drainage kicks in properly but downtime is low enough that most people go eat dinner right after

Laser toning is another one tourists do a lot here

For pigmentation, uneven skin tone, dullness, leftover acne marks etc

When done gently it’s one of the easier lasers to recover from, usually just mild redness for few hours. The problem is some clinics overtreat tourists trying to make the results faster and then the barrier gets completely destroyed

Good laser toning should look gradual, not dramatic after js 1 session

And then there’s skin boosters like skinvive / chanel injections / exosomes etc. These are more for hydration and texture like when people say they want that korean glass skin look, this is usually closer to what they mean

Personally I don’t think these are miracle treatments the way social media makes them sound, especially if someone’s barrier is already damaged. Sometimes simple hydration just looks good because most people are dehydrated and sleep deprived honestly lol

Anyways yeah… if you’re coming to Korea for treatments I really think downtime matters more than people expect. There’s no point doing the strongest procedure possible if you spend the rest of the trip hiding in the hotel with ice packs on your face!!
