The verdict
For texture, dullness and pigmentation, Glycolic Acid is the stronger option, while Lactic Acid is gentler and better suited to sensitive or beginner skin.
Using both? Use with caution Glycolic Acid and Lactic Acid are both exfoliating acids. Layered together they can over-exfoliate, which shows up as stinging, shiny tight skin and breakouts. Pre-formulated blends are fine. Otherwise, use them on different nights. How to layer them →
Glycolic Acid in short
The smallest alpha-hydroxy acid, so it penetrates deepest. It dissolves the bonds between dead skin cells for smoother, brighter skin and fades marks, but it is the AHA most likely to sting.
Lactic Acid in short
A gentler AHA with a larger molecule. It exfoliates while also acting as a humectant, so it suits dry and sensitive skin that cannot tolerate glycolic acid.
