Silk peptides, also known as silk amino acids (SAAs), are a water-soluble mixture of short to medium chain peptides and glycoproteins derived from hydrolysis of raw silk. They are used as an additive in skin and hair care products due to their high levels of serine which has excellent moisture preservation characteristics.
