What it is
Silk is a protein-based ingredient obtained from the fibers spun by the silkworm Bombyx mori, processed for use in cosmetics. In formulas it serves as a skin-conditioning agent and can contribute a smooth, soft surface feel and a refined finish. It appears in finely milled mineral and tone-up sunscreens where a silky after-feel is desired.
Safety & warnings
Silk and silk-derived proteins are generally well tolerated on the skin. Because it is an animal-sourced protein, it is not suitable for vegan formulations, and individuals with a known silk or insect-protein sensitivity should avoid it. It is not associated with comedogenicity at typical use levels.
Origin & sourcing
Animal-derived. It originates from the silk fibers produced by the domesticated silkworm (Bombyx mori), the same source as textile silk, which is cleaned and processed for cosmetic use.
