Science
Mechanism of Action
SR-SPIDER POLYPEPTIDE-1 is a single-chain recombinant polypeptide engineered to replicate specific segments of natural spider silk protein. Its primary mechanism involves acting as a sophisticated film-forming agent, which creates a resilient, protective shield on the skin's surface, effectively guarding against diverse environmental stressors including pollution, UV radiation, and blue-light exposure. Concurrently, it functions as an emollient, imparting a superior sensory profile compared to traditional silicone-based ingredients. The ingredient's biomimetic amino acid structure contributes directly to boosting both the skin's tensile strength and overall elasticity. Its specialized peptide segments are designed to naturally crosslink, forming a hydrophilic powder with potent benefits and silicone-like elastomeric properties. Furthermore, SR-SPIDER POLYPEPTIDE-1 actively supports enhanced skin barrier health, provides robust pollution defense, and offers inherent antioxidation properties. As a bioactive peptide, it plays a crucial role in signaling the body to activate the skin's endogenous repair mechanisms, thereby stimulating cellular regeneration, strengthening dermal structure, and contributing to a visible reduction in the appearance of fine lines and wrinkles.

Key findings
- 01 In targeted skincare applications, a closely related recombinant spider polypeptide (sr-(Wasp Spider Polypeptide-1 Oligopeptide-178)) has been observed to promote a healthy skin appearance, confer a silky-soft texture, and deliver an instant firming effect. Further findings from this study indicate a measurable improvement in skin firmness and elasticity, alongside a reduction in the visible appearance of fine lines and wrinkles.
