About this ingredient
Hydrolyzed Extensin is a hydrolysate of extensin, a plant glycoprotein from the cell wall. In cosmetics it works as a hydrating, film-forming ingredient: it helps hold water at the surface and leaves a thin film that visually smooths skin texture. It appears in serums and creams focused on hydration and comfort. On efficacy, best to stay measured. It provides surface hydration and a sensory effect of smoother skin, but the underlying clinical evidence is limited. It is a supporting hydrating active, useful within a complete formula, not a deep restructuring treatment. For topical use in pregnancy and breastfeeding there are no risk signals. Systemic absorption of a protein hydrolysate from skin is minimal, so it can be used in these stages. Tolerance is good. Low irritation and low allergy potential, compatible with sensitive skin. Most people see no reactions.
