hostel is quite important for me that's why mmv is on top and my mom insisted i keep fmc in the options as well though it's unlikely that someone not getting in mmv will get into fmc.

I completed my profile, applied for B.A. and paid the 300 rs registration fee but I can't see the preference list or anything like that. I want to apply for English honours. Please help this girl out! 🥺🙏

If you have oily, acne-prone skin, you've probably bought a salicylic acid/bha product. A face wash, a serum, a gel. "2% Salicylic Acid" is the standard most brands offer.

But recently I learned one chemistry fact that made me realize almost everything I used was lying to me. The one rule that decides if your BHA works:

Salicylic acid has a pKa of 2.97. At this pH, 50% is in its active free-acid form. The free acid penetrates the pore and exfoliates. The salt form does nothing.

Here's the reality at different pH levels:

· pH 3.0 : ~50% active

· pH 4.0: <10% active

· pH 5.0: <1% active

· pH 5.5+: dead

Now let's look at products popular in the Indian market that oily skin folks reach for.

Minimalist 2% SA + LHA Cleanser: Disclosed pH: 4.5 to 5.0. The salicylic acid is almost completely neutralized. The LHA does mild lifting, but the BHA itself is asleep. You bought a gentle cleanser with a BHA label.

Sebogel (2% SA + 6% Niacinamide): Contains Carbomer. Carbomer needs a pH of 5.5 to 6.5 to hold its gel form. At that pH, salicylic acid is a salt. Sebogel is a functional niacinamide serum. It is not a BHA exfoliant.

Dot & Key CICA 2% Salicylic Acid Gel Cleanser: Carbomer again. Same structural problem. The gel texture proves the pH is too high for free acid activity.

Derma Co 2% Salicylic Acid Face Wash: No pH disclosed. It's a gentle foaming cleanser, which almost always means a pH of 4.5 to 5.5 for skin tolerance. The BHA is likely inactive here too.

Saslic DS (2% SA): A pharmacy product, often recommended by derms. The ingredient list shows a surfactant-based wash. No pH disclosure. The pattern holds.

Why do brands do this? Because a true low-pH BHA stings. It's hard to formulate into a pleasant foaming cleanser or a clear Carbomer gel. So they add the ingredient, set the pH to skin-friendly levels, and sell you a story. The label is technically true. The molecule is in the bottle. It's just chemically dead.

What actually works: A leave-on product with a disclosed pH of 3.0 to 4.0. Paula's Choice 2% BHA Liquid (pH 3.2-3.8) and COSRX BHA Blackhead Power Liquid (pH ~4.0, with gentler betaine salicylate) but they’re more on the expensive side imo. 😢😩

Stop trusting the percentage on the front. Ask the pH. If the brand won't tell you, or the product has Carbomer and feels gentle, your BHA is asleep.
