Acetyl Hexapeptide-37
Acetyl Hexapeptide-37 increases the skin’s moisture content by promoting the formation of the membrane protein aquaporin-3 (AQP3). Because AQP3 forms “water channels” in the cell membranes, the flow of water from the basal layer of the epidermis into the stratum corneum improves. The peptide active also increases collagen I synthesis and keratinocyte proliferation.
