A moisturizing ingredient obtained from natural silk. Some studies have shown that hydrolyzed skin proteins have anti-inflammatory properties.

Humectants are moisturizing ingredients that draw moisture to the skin, either from deeper layers or from the environment (when it's humid).

Hydrolyzed Silk is a humectant ingredient obtained from natural silk. The silk strands are first degummed (to get rid of the outer layer of silk polymer called sericin) and the resulting silk protein called fibroin is then chemically chopped into small peptides (this is called hydrolysis and is usually done by enzymes).
Hydrolyzed silk is more commonly used in haircare products to improve hair texture, but the ingredient also has applications in skincare. Silk proteins can be used as moisturizing humectants because they are able to retain a large amount of water.
There are also reports in scientific literature that hydrolysed silk proteins have anti-inflammatory properties.
