Product Introduction:
Palmitoyl Pentapeptide-4 (Pal-Lys-Thr-Thr-Lys-Ser = Pal-KTTKS) contains 5 amino acids linked to a 16-carbon aliphatic chain for improving the penetration of the molecule through the lipid structures of the skin. It is a matricide. Matrikines are messenger peptides capable of regulating cell activities by interacting with their specific receptors. They activate certain genes involved in the process of extracellular matrix renewal and cell proliferation. By activating the neosynthesis of extracellular matrix macromolecules, palmitoyl pentapeptide-4 provides an anti-wrinkle effect. [medical citation needed] Studies (in vitro and in vivo) demonstrating the anti-wrinkle efficacy of this peptide have been conducted and published by Sederma and by independent organisations.

Application:
skin care-aging, repair.

Usage:
Palmitoyl Pentapeptide-4 helps stimulate collagen synthesis and elastin. The action is very similar to retinol without the irritation.

What are Peptides for Skin Care?
Science has proven that peptides can help manage wrinkles in your skin and reverse the signs of aging. Human skin is comprised mostly of collagen. Collagen is a protein comprised of long segments of amino acids arranged like a chain. Collagen provides a foundation and thickness for skin. Women under 30 have ample collagen, which results in smooth, tight skin. The rest of us have less collagen - skin tends to be thinner, revealing more wrinkles. When collagen breaks down, short segments of amino acids are formed. These are the tiny proteins and active molecules known as peptides. Peptides in skin care can provide significant anti-aging benefits.
