It has many uses in cosmetics and personal care products because of its unique properties.

Chitosan, molecular weight with an average of 300,000 daltons, is extracted from seashells and crab shells. It can be used in many ways in cosmetics.

Chitosan can be used as a moisturizing agent in creams, lotions and serums, helping to improve moisture and skin barrier function.
Its ability to form a film helps create a protective barrier on the skin. Protects skin from environmental stress and pollution.
Chitosan has antimicrobial properties. Therefore, it is useful as a preservative in cosmetic formulas.
