Concern level

High concern

A plant-derived mixture of phytosterols from soybean. In cosmetics, it functions primarily as an emollient and skin-conditioning ingredient, helping improve softness, barrier feel, and moisture retention. It is often used to give a richer, more elegant skin feel than soybean oil while remaining lightweight.
