Sericin Silk Protein

Moisturizing & Conditioning Ingredient for Skin and Hair Care

Sericin is a naturally occurring protein found in silk, where it surrounds and binds silk fibroin fibers. Known for its affinity for moisture, Sericin is used in cosmetic formulations to support hydration, improve softness, and enhance the overall feel of skin and hair.

Its film-forming properties help create a lightweight conditioning layer, making it a useful ingredient in moisturizers, serums, conditioners, and hair treatments.
