Acetyl Hexapeptide-37
Acetyl Hexapeptide-37 increases the skin’s moisture content by promoting increased formation of the membrane protein aquaporin-3 (AQP3). Because this protein forms “water channels” in cell membranes, a higher concentration of aquaporin-3 in the skin improves the flow of water from the basal layer of the epidermis into the stratum corneum. Acetyl Hexapeptide-37 also increases collagen I synthesis and keratinocyte proliferation in the skin.
The effectiveness of this peptide active has already been demonstrated impressively in a number of studies. In one, the moisture content of the skin was increased by 131 % after 56 days of treatment with Acetyl Hexapeptide-37. Study design: 20 women aged between 30 and 50; 2 % Acetyl Hexapeptide-37 formulation; applied twice daily.
