Science
Mechanism of Action
This complex fusion peptide operates by signaling the skin's inherent repair pathways. Its SH-Polypeptide-7 component is designed to emulate human growth hormone, which has been associated with a reduction in fibroblast proliferation and melanin synthesis, potentially contributing to skin brightening, revitalization, and structural support. Concurrently, the SR-SPIDER POLYPEPTIDE-4 segment, a recombinant spider fibroin, is thought to establish a protective film on the skin's surface, while the general peptide structure promotes the natural production of critical matrix proteins like collagen and elastin, thereby supporting cell regeneration.

Safety Profile
The complete fusion ingredient, METHIONYL SH-POLYPEPTIDE-7 DIPEPTIDE-19 SR-SPIDER POLYPEPTIDE-4 HEXAPEPTIDE 40, has not undergone specific safety reviews by regulatory bodies such as CIR, SCCS, or FDA. However, its individual component, SH-Polypeptide-7, is noted to be suitable for various sensitive applications (e.g., Teen SAFE, Baby SAFE, Eyelid SAFE) by SkinSAFE, and generally considered free from common irritants. Broader categories of peptide hydrolysates are often granted 'Generally Recognized as Safe' (GRAS) status by the FDA.
