Science
Mechanism of Action
This polypeptide is theorized to function by signaling to the skin's endogenous repair mechanisms, thereby stimulating regeneration and reinforcing skin structure. While direct mechanistic data for METHIONYL SH-POLYPEPTIDE-92 is limited, related polypeptides are known to enhance collagen and elastin synthesis, leading to improved firmness and elasticity, increased moisture retention, and a visible reduction in fine lines and wrinkles. Some polypeptides also demonstrate capabilities in inhibiting melanin production for brightening and exhibiting anti-inflammatory benefits.

Stability
Polypeptides generally require careful handling, benefiting from sterile and oxygen-free water or buffer solutions, such as Tris or phosphate buffer, ideally at pH 7. Brief sonication can assist in dissolution and minimize aggregation. Gentle warming may help if precipitation occurs, though excessive heat should be avoided. Overall, polypeptides are susceptible to physicochemical instability from harsh temperatures and extreme pH conditions.
Safety
Safety Profile
No specific safety assessments by regulatory bodies such as CIR, SCCS, or FDA have been found for METHIONYL SH-POLYPEPTIDE-92. While the CIR has reviewed broader categories of ingredients like dimethicone polymers and general tissue-derived proteins/peptides, there is no direct evaluation for this specific polypeptide.
