Silk Amino Acids

Silk Amino Acids is a blend of amino acids derived from hydrolyzed silk protein, used as a humectant and conditioning agent for skin and hair.

What it is

Silk Amino Acids is produced by fully hydrolyzing silk protein, typically from the silkworm cocoon, into its constituent amino acids such as glycine, alanine, and serine. The resulting small, water-soluble molecules act as humectants that help skin and hair hold moisture and feel smooth. They are valued for a light, non-greasy conditioning effect and good water solubility.

Safety & warnings

Generally well tolerated and considered low risk for irritation at cosmetic levels. Being silk-derived, it is not suitable for those avoiding animal-sourced ingredients; reported sensitization is uncommon.

Origin & sourcing

Animal-derived: obtained by hydrolyzing silk protein produced by silkworms (Bombyx mori).
