None

Skin Benefits

Provides a silky, cushioned feel and reduces the look of surface roughness, and helps limit water loss by forming a flexible film.

Uses In Skincare & Cosmetics

Used in hydrating serums, sheet masks, and makeup primers to lay down a light, protective veil and improve slip.

Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

Generally well tolerated with low irritation potential. Those sensitive to silk proteins may react; patch testing is advisable for known silk/textile allergies.

Is Sericin a Good Ingredient?

Good, because it's a reliable film-former that reduces water loss and improves surface smoothness. Most of the supporting evidence is in vitro or from small cosmetic tests, so the effects are real but subtle rather than clinically proven at a larger scale, which is why it sits at Good.
