SR-TIGER POLYPEPTIDE-1.

Insufficient Data / NOT REPORTED

While identified as SR-TIGER POLYPEPTIDE-1, current available research refers to SR-Spider Polypeptide-1, a single-chain recombinant peptide synthetically produced via fermentation and derived from the gene coding for fibroin-4 of the Araneus diadematus spider silk protein. This innovative peptide acts as a protective barrier against environmental aggressors like pollution and UV radiation, while simultaneously functioning as an emollient to enhance skin texture and deliver an instant firming sensation.

Science

Mechanism of Action

SR-TIGER POLYPEPTIDE-1, in its documented form as SR-Spider Polypeptide-1, is a bioengineered peptide that mimics a specific segment of natural spider silk protein. Its primary mechanism involves forming a non-occlusive, protective film on the skin and hair, thereby shielding against detrimental environmental factors such as pollution, ultraviolet radiation, and blue light spectrum exposure. Concurrently, it functions as an emollient, imparting a superior sensory profile compared to traditional silicone-based ingredients, resulting in a silky-soft texture. Furthermore, this peptide is understood to signal the body's inherent repair pathways, promoting the regeneration of mature skin cells, fortifying the dermal structure, and contributing to a visible reduction in wrinkle appearance. Its rapid biodegradability also ensures compatibility with the skin's natural microflora.
