SR-(WASP SPIDER POLYPEPTIDE-1 OLIGOPEPTIDE-178).

Valuable / DISPERSING NON-SURFACTANT, FILM FORMING, SKIN CONDITIONING, SKIN PROTECTING

SR-(WASP SPIDER POLYPEPTIDE-1 OLIGOPEPTIDE-178) is a pioneering single-chain recombinant polypeptide, bio-engineered from spider silk protein via fermentation. It functions as a multi-tasking ingredient, forming a protective barrier while enhancing skin texture and signaling endogenous protein production.

Science

Mechanism of Action

This advanced recombinant polypeptide creates an imperceptible protective film on the skin's surface, acting as a shield against environmental aggressors, including particulate pollution, UV radiation, and blue light. Beyond external defense, it functions as an exceptional emollient, delivering a smooth, non-silicone sensory experience. As a bioactive peptide, it is recognized for its capacity to stimulate the skin's natural protein synthesis, specifically collagen, and is hypothesized to engage intrinsic repair mechanisms, thereby fortifying the skin barrier and contributing to overall formulation integrity.
