About Glycolic Acid (AHA)

Glycolic acid is an AHA used for dullness, rough surface texture and uneven-looking skin. It works on the skin's surface, so it can help improve smoothness and radiance when used correctly. It is best suited to skin that can tolerate exfoliation and is protected with daily SPF.

Key Technology

Glycolic acid may appear with lactic acid, salicylic acid, PHA, polish formats or peel pads. The strength and format matter: a cleanser, pad and leave-on treatment will feel very different. PHA support can make some exfoliating formulas feel gentler, but overuse can still irritate.

How to Choose

Start with a rinse-off or occasional-use formula if you are new to acids. Use leave-on glycolic products carefully and avoid stacking with retinol or other strong exfoliants at first. If the skin becomes shiny, tight or stingy, reduce use and rebuild with moisturiser.

Glycolic Acid (AHA) FAQs

Common questions about Glycolic Acid (AHA) products and routines.

What is glycolic acid best for?
Glycolic acid is mainly a surface-renewing AHA, so it is best suited to dullness, rough texture and uneven-looking skin rather than oily pores alone. It can make skin feel smoother, but it is also more likely to irritate if overused. Sensitive skin may prefer PHA or lower-frequency exfoliation.
How often should I use glycolic acid?
Follow the product instructions, but if you are new to glycolic acid, begin less often than daily. Leave-on creams, pads and peels can feel much stronger than rinse-off cleansers. If skin becomes shiny, tight, flaky or stingy, reduce frequency and use moisturiser until the barrier feels normal.
Can glycolic acid be used with retinol?
It can be part of the same overall routine, but not necessarily on the same night. Many skins tolerate glycolic acid and retinol better when alternated. Using both too aggressively can damage the barrier and increase sun sensitivity. Keep SPF consistent and simplify the routine if dryness or redness appears.
