Glycolic Acid Polymer
What is Glycolic Acid Polymer?
Glycolic Acid Polymer is a synthetic polymer created through the esterification of glycolic acid, an alpha-hydroxy acid originally sourced from natural materials like sugarcane. In cosmetic formulations, it serves primarily as a humectant, buffering agent, and skin conditioning ingredient. As a humectant, it attracts and binds water to the skin's surface, promoting sustained moisture. Its buffering properties help stabilize product pH for better compatibility and efficacy. The polymer structure forms a lightweight film that smooths the skin's texture and enhances the sensory feel of creams, lotions, serums, and cleansers. This form reduces the penetration rate compared to monomeric glycolic acid, potentially offering gentler application in daily skincare routines focused on hydration and conditioning.
