Science
Mechanism of Action
As a low molecular weight lipo-peptide derived from Pro-EGF, Palmitoyl sh-Tripeptide-3 Amide targets and binds to the Epidermal Growth Factor Receptor (EGFR). This specific binding initiates a cascade of cellular activities, promoting the robust growth, proliferation, and differentiation of both keratinocytes and dermal fibroblasts. Crucially, it significantly upregulates the endogenous production of essential structural proteins such as collagen and elastin, while also actively attracting reparative cells to sites of micro-damage. This multifaceted action supports comprehensive skin repair, improves firmness, and diminishes the visible signs of aging. Additionally, it functions as a humectant and skin-protecting agent.
