Hydrolyzed silk is a protein derived from natural silk fibers that has been broken down into smaller peptides or amino acids. This process allows it to be more easily absorbed by the skin and hair. It is commonly used in cosmetics for its conditioning, moisturizing, and film-forming properties, helping to improve the texture and appearance of skin and hair.

On the skin, hydrolyzed silk acts as a humectant, drawing moisture from the air to hydrate the skin. It can also form a light, breathable film that helps to reduce moisture loss and improve skin smoothness.
How does hydrolyzed silk benefit hair?
In hair care, hydrolyzed silk penetrates the hair shaft to condition and strengthen strands, reducing breakage. It also imparts shine, improves elasticity, and helps to repair damaged hair, making it feel softer and smoother.
