Our take
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.
What it does
Skin Benefits
Provides a silky, cushioned feel and reduces the look of surface roughness, and helps limit water loss by forming a flexible film.
Where you'll find it
Uses in Skincare & Cosmetics
Used in hydrating serums, sheet masks, and makeup primers to lay down a light, protective veil and improve slip.
Before you use it
Safety
Generally well tolerated with low irritation potential. Those sensitive to silk proteins may react; patch testing is advisable for known silk/textile allergies.
