Palmitoyl Myristyl Serinate
What is Palmitoyl Myristyl Serinate?
Palmitoyl Myristyl Serinate is a synthetically derived ester formed from palmitic acid, myristyl alcohol, and the amino acid serine. Classified as an emollient and skin-conditioning agent, it structurally resembles ceramides, the lipids naturally present in the skin's outermost layer. In cosmetic formulations such as moisturizers, creams, and lotions, it works by embedding into the intercellular spaces of the stratum corneum, aiding in the reinforcement of the skin's lipid barrier. This function helps formulations spread smoothly while contributing to the maintenance of skin's moisture balance and suppleness. Developed to replicate human skin lipids, it supports product efficacy in hydration-focused regimens without altering pH or causing disruption.
