Shop verified exfoliators →Glycolic acid is an AHA (alpha hydroxy acid) — the smallest acid molecule, so it penetrates well and is the most effective exfoliant for surface glow and texture. It’s powerful, which means it’s also easy to overdo.
What it does
AHAs work on the skin surface: they dissolve the “glue” holding dead skin cells, revealing brighter, smoother skin. Over time, glycolic acid helps with dullness, rough texture, fine lines, and post-acne dark spots.
AHA vs BHA — which do you need?
- AHA (glycolic): surface glow, dryness, dullness, sun damage, dark spots. Better for normal/dry skin.
- BHA (salicylic): goes inside pores — better for oily, acne, blackheads. (See the BHA guide.)
How to use it (Bangladesh)
- Use at night, start 1–2 times a week, build up slowly.
- Sunscreen the next day is non-negotiable — AHAs make skin much more sun-sensitive, and in BD’s strong sun that means new dark spots if you skip it.
- Follow with a ceramide moisturizer to protect the barrier.
What not to mix
Don’t layer glycolic acid with retinol, BHA or vitamin C on the same night — alternate them. (See layering order.) During pregnancy, low-% glycolic is generally considered fine, but check with your doctor.

Frequently asked questions
What does glycolic acid (AHA) do?
It exfoliates the skin surface by dissolving the bonds between dead skin cells, improving dullness, rough texture, fine lines and post-acne dark spots. Best for normal to dry skin.
AHA or BHA — which should I use?
Use AHA (glycolic) for surface glow, dryness and dark spots; use BHA (salicylic) for oily, acne-prone skin and blackheads since it works inside the pore.
Do I need sunscreen with glycolic acid?
Yes, absolutely. AHAs increase sun sensitivity, so daily sunscreen is non-negotiable — skipping it in Bangladesh’s strong sun can cause new dark spots.
Where can I buy authentic glycolic acid in Bangladesh?
At TheSkinProof — every AHA product is invoice-verified, batch-checked and climate-stored, with a 2× money-back guarantee against counterfeits.
Is glycolic acid safe for sensitive skin?
It can be used on sensitive skin, but start with a low concentration once or twice a week and stop if you notice redness or stinging that does not settle quickly.
How do I spot a fake glycolic acid toner?
A fake toner may smell or feel different from the genuine formula and often has a batch code that does not match the box. Buy from a seller who can show a verifiable batch code before you trust it on your face.
