Science
Mechanism of Action
Upon topical application, SH-PENTAPEPTIDE-11 SP, also identified as Acidic Fibroblast Growth Factor (aFGF), selectively binds to specific receptors on fibroblasts. This interaction initiates a cascade of cellular activities that accelerate cell proliferation and tissue regeneration. It significantly boosts the synthesis of crucial structural proteins like collagen and elastin, thereby fortifying the skin's extracellular matrix. Additionally, it exhibits powerful antioxidant properties, effectively neutralizing free radicals, mitigating cellular aging, and preventing programmed cell death and functional decline.

- Beta-hydroxy acids (BHAs)
Safety
Safety Profile
While a general Cosmetics Ingredient Review (CIR) panel statement suggests peptides are safe for topical use below 10 parts per million (ppm), specific safety assessments by CIR, SCCS, or FDA for SH-PENTAPEPTIDE-11 SP are currently unavailable. Despite this, it is generally considered a safe, effective, and well-tolerated ingredient for skin application.
