Mechanism of action

Dapsone works through dual mechanisms: as an antimicrobial agent targeting bacterial folate synthesis, and as an immunomodulator that reduces neutrophil-mediated inflammation. In topical gel formulation, it penetrates skin to suppress inflammatory pathways relevant to acne and other dermatological conditions. The anti-inflammatory effects are particularly useful in conditions driven by neutrophil activation and oxidative stress.
