Use in Cosmetics

Mucin (highly glycosylated protein produced by the cells of the epithelial tissues of the metazoans in their body) It is a protein responsible for maintaining hydration levels and provides lubrication and anti-adhesive properties between cells. Numerous studies since 1900 demonstrate its properties:
