Science & Benefits
Chitosan is a natural polysaccharide derived from the shells of crustaceans. It is a powerful film-forming humectant with unique 'mucoadhesive' properties, meaning it bonds to the skin surface to provide a long-lasting moisture barrier. It is zero-comedogenic and possesses mild antimicrobial properties. For acne patients, it acts as a 'biological bandage,' providing a sterile, hydrated environment that accelerates the healing of lesions while physically protecting the skin from external irritants.
