Science
Mechanism of Action
This polypeptide is believed to function as a cellular messenger, influencing key dermal processes. Drawing parallels with related SH-polypeptides (e.g., SH-Polypeptide-1, -5, -9), it is hypothesized to stimulate cellular activities such as accelerating skin cell turnover, boosting the synthesis of structural proteins like collagen and elastin, and supporting the skin's natural wound healing mechanisms. These actions collectively aim to enhance skin elasticity, promote overall skin renewal, and improve epidermal hydration.

Stability
As a recombinant peptide with a relatively large molecular structure, SH-POLYPEPTIDE-92 likely requires sophisticated delivery systems, such as liposomes or nanoparticles, to optimize its stability, penetration, and efficacy within topical applications. Peptides are generally susceptible to physicochemical degradation, necessitating protective formulation strategies to maintain product shelf-life and ingredient integrity.
Safety
Safety Profile
Specific safety assessments by CIR or SCCS for SH-POLYPEPTIDE-92 are not available. The FDA mandates cosmetic ingredient safety but does not pre-approve them. However, safety studies on related peptides, such as SH-Polypeptide-1, applied topically have shown no significant irritation, general toxicity, or adverse effects. Paula's Choice identifies SH-POLYPEPTIDE-92 as 'generally non-irritating', aligning with the expectation that manufacturers ensure adherence to broader cosmetic safety regulations for peptides.
