Mechanism of action

Adapalene binds to retinoic acid receptors to regulate keratinocyte differentiation and reduce comedone formation. Benzoyl peroxide acts as an oxidizing agent that generates reactive oxygen species to eliminate Cutibacterium acnes (formerly Propionibacterium acnes) and reduce bacterial resistance. The combination provides complementary mechanisms targeting both inflammatory and comedonal acne.
