Mechanism of action

Minocycline is a broad-spectrum tetracycline antibiotic that works through multiple mechanisms in acne treatment: it inhibits bacterial protein synthesis to reduce Cutibacterium acnes (formerly Propionibacterium acnes) proliferation, and it also has anti-inflammatory properties that suppress cytokine production and neutrophil activation independent of its antimicrobial effects. The 4% foam formulation provides topical delivery to affected skin areas while minimizing systemic absorption.
