Mechanism of Action
This potent pentapeptide functions as a cell-communicating and skin-identical ingredient. Its primary mechanism involves positively influencing the synthesis of Microfibril-associated glycoprotein 4 (MFAP-4), a crucial regulator in the organization of elastin and the formation of robust elastic fibers. Simultaneously, SH-Pentapeptide-3 stimulates overall collagen and elastin production, contributing to improved skin architecture and resilience. Beyond these foundational actions, it is described to visibly diminish fine lines and wrinkles, enhance skin firmness and elasticity, support optimal moisture retention, brighten skin tone through melanin inhibition, and possess anti-inflammatory and wound healing properties.

Stability
For optimal stability during storage, solutions containing SH-Pentapeptide-3 are generally best maintained at a slightly acidic pH, typically ranging between 5 and 6. To preserve its integrity during formulation, incorporation into cosmetic products should ideally occur at temperatures below 40°C.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated SH-PENTAPEPTIDE-3. However, related pentapeptides, such as Myristoyl Pentapeptide-4, Palmitoyl Pentapeptide-4, and Pentapeptide-4 (KTTKS and KTSKS sequences), have been deemed safe for use in cosmetics by the CIR. The FDA typically does not pre-approve individual cosmetic ingredients.
