Using both? Safe to mix There is no known chemical conflict between Hydroquinone and Kojic Acid, and neither makes the other less effective. They share a goal (pigmentation), so together they reinforce each other. How to layer them →
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).
Kojic Acid in short
Derived from fungi used in rice wine and soy sauce production, kojic acid blocks the enzyme that makes melanin. It is effective on dark spots but can cause contact sensitivity in some people.
