1.MECHANISM OF ACTION
Palmitoyl Tetrapeptide-20 penetrates the skin and acts on fibroblasts to stimulate the synthesis of key structural proteins including collagen, elastin, and fibronectin, while also enhancing the integrity of the dermal-epidermal junction. Its palmitoyl chain facilitates efficient delivery into the dermis, where it modulates extracellular matrix remodeling and reduces the activity of matrix-degrading enzymes, resulting in improved skin firmness and reduced wrinkle depth.
2.PRODUCT INDICATIONS
This peptide is indicated for research and development of topical cosmetic formulations targeting skin aging, loss of firmness, and wrinkle reduction, including anti-aging serums, firming creams, and eye contour treatments. It is suitable for products aimed at mature skin, photoaged skin, and areas prone to sagging such as the neck and décolletage, as well as for in vitro and ex vivo models evaluating collagen production and skin elasticity.
