Ingredient
Glycolic Acid (AHA)
Glycolic acid (AHA) loosens the bonds between dead skin cells so they shed faster, revealing smoother and more even-toned skin underneath. It’s the smallest AHA molecule, which means it penetrates deeper than other AHAs like lactic acid. Look for 5–10% for regular use — start at 5% a few times a week and work up. Always use sunscreen the morning after, as glycolic acid makes skin more sensitive to UV.
Ingredient
Suitable for
Dull or uneven skin tone with dark spots or texture — glycolic acid is one of the most effective surface exfoliants for fading hyperpigmentation and smoothing rough patches, with visible results typically starting around 6–8 weeks.
Also suitable for oily Skin, dry Skin, combination Skin and mature Skin.

Combinations that work
- Hyaluronic AcidHydrating
Glycolic acid loosens the bonds between surface cells and raises water loss for several hours afterwards. Hyaluronic acid applied straight after replaces what the exfoliation cost.
- CeramidesRepairing
Glycolic acid removes surface lipids along with the dead cells. Ceramides applied the same evening put them back, which is what keeps regular exfoliation from turning into a compromised barrier.
Combinations to avoid
Layering an AHA over retinol doesn't accelerate results — it over-exfoliates the barrier. Cells are shed faster than they can be replaced, and the outcome is sensitisation and redness. Alternate nights.
AHA exfoliates the surface, BHA works inside the pore — using both in one session is not more thorough, it is simply more exfoliation than the barrier can absorb. Alternate them across the week.
Two low-pH products back to back is a large irritation load for a small gain. An AHA can improve vitamin C penetration, but only skin that already tolerates both should try it. Vitamin C in the morning, the acid at night.
