Shop acne-care products →Salicylic acid (a BHA — beta hydroxy acid) is the gold-standard ingredient for oily, acne-prone and congested skin — exactly the kind of skin Bangladesh’s heat and humidity create. Here’s how to use it well.
What it does
BHA is oil-soluble, so it goes *inside* the pore and dissolves the oil, dead skin and gunk that cause blackheads and breakouts. It also calms inflammation.
Best for
Oily/combination skin, blackheads, whiteheads, clogged pores, body/back acne, and the BD “sweaty T-zone.” (See acne guide.)
How to use it (without over-drying)
- Start 2–3 nights a week, then build up as tolerated.
- Common strength: ~2% BHA.
- Always follow with moisturizer; sunscreen is a must the next day (acids increase sun sensitivity).
What not to mix
- Avoid using strong BHA + retinol + vitamin C all at once — alternate nights to prevent irritation. (See layering order.)
- During pregnancy, high-strength BHA is usually avoided (see pregnancy-safe guide).

Can I use BHA if I sweat a lot in Dhaka's heat and humidity?
Yes, BHA actually suits oily, sweaty skin well since it works inside the pore, but apply it at night and always follow with sunscreen the next morning since it increases sun sensitivity.
How do I spot a fake salicylic acid product?
A fake often has an off smell, a texture that feels different from the real formula, and a batch code that does not match between the bottle and box. Buy only from a seller who can show a verifiable batch code.
