Phytosterols
What is Phytosterols?
Phytosterols are naturally occurring steroid alcohols found in plants, such as vegetable oils, nuts, and seeds, chemically akin to cholesterol in human skin. These lipid-like compounds are widely used in skincare formulations as conditioning agents, particularly emollients. They function by integrating with the skin's intercellular lipids, helping to reinforce the protective barrier and reduce transepidermal water loss. This action promotes skin suppleness and a smooth texture without greasiness. In products like moisturizers, lotions, and barrier creams, phytosterols also aid in stabilizing emulsions, ensuring even distribution and consistent performance. Their biocompatibility makes them suitable for daily use across various skin types, contributing to overall skin comfort and resilience.
