Using both? Safe to mix There is no known chemical conflict between Glycolic Acid and Hydroquinone, and neither makes the other less effective. They share a goal (pigmentation), so together they reinforce each other. 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.
Hydroquinone in short
The strongest topical depigmenting agent, used for melasma and stubborn dark spots. It blocks melanin production, but it must be used in short, supervised courses: long-term use can cause irritation and, rarely, ochronosis (blue-black darkening).
