With retinal, how much you use matters, but so does what you put down first. Starting retinal on an unprepared barrier means you take on more of the adjustment-period irritation than you need to.

This routine is for retinoid beginners, or skin that gets irritated easily by actives.

Step 1. Barrier Shield Serum

Brand D — Birch sap, panthenol, niacinamide

A layer applied before retinal. It can help slow absorption and reduce early irritation, though it's not a required step — depending on your skin, you can adjust the order or skip it.

Step 2. Mild Retinal Serum

[PM only] Brand M — Retinal 100ppm, madecassoside, cica

This is the step that actually drives turnover. If it's your first time, mix a small amount with the Step 3 cream to start, and go twice a week for the first 1-2 weeks before increasing frequency. Night use only — sunscreen the following morning is necessary.

Step 3. Barrier Moisturizing Cream

Brand A — Ceramide capsules

This step offsets the dryness and irritation that can come with retinal use. Enough hydration can make the adjustment period noticeably easier to get through.

Step 4. UV Shield Sunscreen

[AM only] Brand B — Rice extract 30%, grain fermented extracts

Retinoids don't directly cause photosensitivity, but during the adjustment period the skin barrier can thin and become more reactive, making it more vulnerable to UV. That's why sunscreen matters especially during this phase.

In short — you prep the barrier, drive turnover, keep it hydrated, and protect it from UV.

The exact order or how you combine these can shift depending on your skin, but all four roles need to be covered to get through the adjustment period comfortably.

With a budget like that, I think I’d focus less on squeezing in as many products as possible and more on figuring out which steps I could realistically leave out depending on skin type.

For sensitive or dry skin, I’d probably keep the basics: cleanse with something from K-beauty Brand R, moisturize with a product from Brand E, and finish with sunscreen from Brand S. In that case, toner, essence, and serum would probably be the first things I’d cut.

For combination or oily skin, though, I think there’s another way to do it.

You could cleanse with Brand C, use a light soothing toner from Brand A, and then finish with a hydrating sunscreen from Brand B.

Instead of adding a separate moisturizer, I’d let the sunscreen do more.

If the sunscreen already gives you enough hydration, it can handle part of that moisturizing role while still giving you sun protection. With a $30 budget, that kind of multitasking can make a lot of sense.

Of course, I wouldn’t suggest skipping moisturizer for someone with very dry skin. What you can leave out really depends on your skin type and the formulas you’re using.

So I’m curious:

If you only had $30, what would you skip first?

Toner? Serum? Moisturizer? Or something else?

Scrolling through TikTok and Instagram, I’ve noticed the ways people split up their routines are more varied than I expected.

Not just skin type or skin concerns — some routines are built around specific ingredients, some are for when the seasons change, and I’ve seen a ton of flight routines.

Climate-related ones are all over the place too. Moving from one place to another — humid to dry, or the other way around — and figuring out what to swap out.

Watching this stuff is entertaining, but it also feels a little off. Like there’s some value I’m getting from it even when the situation has nothing to do with me (say, I barely fly and I’m still watching a long-flight routine). It’s not even matched to my skin type or my local weather.

So I’ve been wondering — is this actually useful, or is it just fun to watch other people’s routines? Maybe it’s just me.

There might not be two more opposite Vitamin C products in K-beauty. One goes all-in on the strongest possible form. The other deliberately gives that strength up. Yet both are flagship products for their brands.

----------------------------------------------------------------------------------------------------------

Corner 1 — K-Beauty Brand C: "23% Pure Vitamin C"

Concentration: 23% (top-tier in the market)

Form: Pure Ascorbic Acid

Paired with: Vitamin E + Glutathione for antioxidant support

Positioning: "Come here if you've already used Vitamin C before." No hand-holding for beginners. Built for targeted dark spot correction.

Pure Vitamin C is well-researched and effective, but it's also relatively unstable and can feel irritating depending on your skin. The brand doesn't hide this — it's not the gentle option, it's the go-hard one.

Corner 2 — K-Beauty Brand B: "Gentle Vitamin C"

Concentration: Not disclosed (not even the focus)

Form: Vitamin C derivative

Paired with: Centella Asiatica extract for soothing

Positioning: "Layer it in morning and night, no second-guessing." Built to be sensitive-skin friendly.

A Vitamin C derivative is essentially the same active with a slightly modified structure — traded off for more stability and easier everyday use. That's why this brand positions it as the "no-sting" Vitamin C.

---------------------------------------------------------------------------------------------------------

So which one wins?

Here's the twist — they're not even playing the same game.

23% pure Vitamin C works best if: you've used Vitamin C before and want a targeted, intensive approach to dark spots and dullness. Start small and adjust frequency if you notice irritation.

Gentle Vitamin C works best if: you're new to Vitamin C, have sensitive skin, or just want something you can layer in every day without thinking twice.

Higher concentration doesn't automatically mean better. What actually matters is which one fits your skin and your routine.

If you're using a Vitamin C at a different concentration or in a different form, let me know in the comments.

When you look at K-beauty products with niacinamide as a key ingredient, the concentrations vary quite a bit.

So I compared a few products currently on the market by concentration, and what stood out wasn’t the percentage itself, but what the niacinamide was paired with.

2% — Glow Serum
Niacinamide + Propolis
→ Focused on soothing and hydration

5% — Dark Spot Correcting Glow Serum
Niacinamide + Squalane
→ Dark spot care with barrier support and hydration

10% — Niacinamide 10 + TXA 4 Serum
Niacinamide + TXA 4%
→ More focused on hyperpigmentation and uneven skin tone

15% — The Niacinamide 15 Serum
Niacinamide + Zinc PCA
→ More focused on oil, sebum, and pore care

Even though they all feature niacinamide, the other ingredients they’re paired with give each product a pretty different direction.

When choosing a niacinamide product, do you look at the percentage first? Or do you pay more attention to what it’s formulated with?

And if you’ve tried a niacinamide product above 15%, I’d love to hear about it.

*I intentionally left out the brand names.

Sebum softeners keep showing up lately, and the thing is they’re not cleansers.

You put it on before washing, then you wash.
Which is strange, because that’s what oil cleansing was supposed to be doing.

Dissolving hardened sebum with oil. So the fact that there’s now a separate product for it makes me wonder if oil cleansers were never really handling that part.

Or maybe oil cleansers were always just for makeup, and sebum was a different problem the whole time.

For anyone who’s used one — does it actually feel different from oil cleansing? Or is it the same thing with a new name?

And are you using it instead of your oil cleanser, or doing both?

I recently came across an interesting retinol product.
Most retinol products are serums or creams, but this one took a different approach.

Instead, it was designed as an overnight mask that you apply before bed and remove the next morning.

It got me thinking.
Retinol is well known for its effectiveness, but many people also stop using it because of irritation or because it can be difficult to incorporate into their routine.

So I started wondering if simply changing the format—not the ingredient itself—could make a meaningful difference.

I don’t know whether this type of product actually reduces irritation. But I have to admit, it immediately made me think, “I’d like to try that.”

It also made me wonder whether the same idea could work for other active ingredients, such as Vitamin C or Azelaic Acid.

I recently came across a product that positioned retinol as an “overnight treatment you apply before bed,” and I honestly thought it was a pretty smart idea.

Retinol is well known for its benefits, but a lot of people also find it intimidating because of irritation and the learning curve.

By leading with the experience of “overnight care” instead of simply saying “retinol,” it felt much more approachable.

It made me wonder…
Could the same concept work for other ingredients too?

I’m thinking of ingredients like Vitamin C, Azelaic Acid, AHA/BHA/PHA, Tranexamic Acid, or even Hydroquinone.

Personally, I’d love to see something like this for Azelaic Acid or Vitamin C. Framing it as an overnight ritual feels much more appealing than focusing on the ingredient itself.

What ingredient do you think would work best with this kind of “overnight routine” concept?

I never expected skincare to become a hobby, but learning about routines has become strangely addictive.

These days I ask AI questions, browse products at Olive Young and pharmacies, read ingredient lists, and spend way too much time comparing product pages just to see what works well together.

At first, I was only thinking about routines for different skin types or skin concerns. But then I realized there are routines for different climates, different weather, travel, morning vs. night, and even different stages of using an ingredient. Some ingredients seem to need one routine while your skin is adjusting, and a different one once your skin has adapted.

The more I break skincare down this way, the more fun it becomes. It almost feels like browsing Netflix or Spotify—except instead of discovering movies or music, I’m discovering new routines.

And the best part is that I keep discovering products and ingredients I probably never would have noticed if I had looked at them individually. Seeing products in the context of a routine completely changes how I think about skincare.

Am I the only one who finds building routines more interesting than buying products?

I've noticed that some people don't use toner at all—they just go straight from cleansing to serum or moisturizer.

Others say toner is an essential part of their routine and they'd never skip it.

So I'm curious.

Do you think toner is actually necessary?

Or is it one of those products that works for some people but isn't essential for everyone?

I'd love to hear why you use it—or why you don't.

10-step routine
Slugging
Double cleansing
Morning Vitamin C
Something else? (Leave a comment!)

If you had to remove just one product from your routine forever, what would it be?

-Eye cream?
-Toner?
-Sheet mask?
-Essence?
-Cleansing water?
-Something else?

I’m not asking which one is bad—just which one you personally could live without, and why.

Curious to see what everyone picks. 👀

But lately I've been wondering if the problem isn't always the product itself. Maybe we just give up on products too quickly.

We'll try something for a few days, decide it's not working, switch to something else, and then repeat the cycle. Sometimes I wonder if we never give a product enough time to actually know whether it works for us.

Of course, if a product is causing irritation or making things worse, stopping makes sense. But for everything else, how long do you usually stick with a new product before deciding it's not for you?

One piece of advice I see all the time in skincare communities is: “Stop all actives and focus on repairing your skin barrier first.”

But I’m not sure that’s always the right approach.

For example, if your original concerns were acne, clogged pores, or post-acne hyperpigmentation, does stopping all actives actually help? Or does it sometimes just prolong the original problem?

It seems like some people switch entirely to barrier-supporting ingredients like ceramides, panthenol, and cica when their skin is irritated.

Others, however, keep using actives such as retinoids, vitamin C, or azelaic acid, but reduce the frequency or strength instead of stopping completely.
I’m curious what has worked best for you.

Most of the time, we think about skincare ingredients individually. But this image looks at them more like wine and food pairings, focusing on how certain ingredients work well together.

It got me wondering whether routines could be built not only around skin concerns, but also around ingredient pairings. For example, creating a routine with products containing ingredients that complement each other, such as BHA + Niacinamide or Oat + Centella.

Do you consciously think about ingredient combinations when building your routine, or do you mostly focus on individual products?

What if there were skincare routines designed specifically for lazy people?

Something like this:

Lazy Glow Routine
3 steps: Toner Pad → Serum → Sunscreen
"Lazy, but still making an effort."

Lazier Glow Routine
2 steps: Serum → Sunscreen
"Doing the bare minimum."

Laziest Glow Routine
1 step: Sunscreen
"If you're only going to use one product, make it sunscreen."

The idea is simple: the less motivation you have, the fewer steps you follow — but you still do something for your skin.
