What is Glycine Soja (Soybean) Sterols?

Glycine Soja (Soybean) Sterols are phytosterols extracted from soybeans, primarily beta-sitosterol, campesterol, and stigmasterol. These natural lipids resemble cholesterol found in human skin, allowing them to integrate into the stratum corneum's lipid barrier. In cosmetic formulations like creams, lotions, and balms, they act as emollients by smoothing surface irregularities and enhancing product spreadability. As skin conditioning agents, they promote suppleness by mimicking skin's natural oils, aiding in hydration retention without greasiness. Derived from renewable soybean sources, they provide a plant-based alternative to synthetic emollients, contributing to barrier reinforcement in leave-on products.
