Hydrolyzed Silk

Description

Hydrolyzed Silk is a highly prized ingredient in skincare formulations, derived from the protein fibers of silkworm cocoons. This water-soluble form of silk is created through a hydrolysis process, breaking down the large protein molecules into smaller, more easily absorbed peptides and amino acids. The resulting ingredient boasts a molecular weight typically ranging from 300 to 5,000 Daltons, allowing for effective penetration into the skin's upper layers.

Known for its exceptional moisturizing properties, Hydrolyzed Silk forms a protective film on the skin's surface, helping to reduce transepidermal water loss and improve hydration. It also exhibits notable film-forming capabilities, contributing to a smooth, silky texture in skincare products. The amino acid composition of Hydrolyzed Silk closely resembles that of human skin, making it particularly compatible and beneficial.

In addition to its hydrating effects, Hydrolyzed Silk has been shown to possess antioxidant properties, potentially offering protection against free radical damage. It may also aid in improving skin elasticity and suppleness. Typically used at concentrations between 0.5% to 5% in formulations, this versatile ingredient is found in a wide range of products, including moisturizers, serums, hair care items, and color cosmetics.
