Ingredient overview

What is Glycolic Acid?

Glycolic acid is the smallest commonly used alpha hydroxy acid, which contributes to efficient penetration through the stratum corneum. In appropriately formulated products it is used for surface exfoliation, texture smoothing and support for uneven pigmentation.

Its relatively strong penetration also means glycolic acid can be more irritating than gentler-feeling exfoliants for some users. Product pH and free-acid concentration are more informative than the percentage number alone when judging strength.

Routine guidance

How to use it

Start glycolic-acid leave-on products gradually, usually at night, unless the product is designed for daily use. Follow with moisturizer and use sunscreen consistently.

Pairing guidance

Routine compatibility

Pair with glycerin, panthenol, ceramides and other barrier-support steps. Using strong glycolic acid with retinoids or multiple exfoliants at once can increase irritation.

Formula context matters

Good to know

Overuse can cause stinging, dryness and barrier disruption. Professional-strength peels are very different from low-strength home skincare.
