Concern level

High concern

Soybean sterols are a mixed phytosterol fraction derived from soybean lipids and used in cosmetics as an emollient, skin-conditioning, and barrier-supporting ingredient. They are widely described as helping reinforce the skin barrier and improve moisture retention, and CIR-reviewed soy-derived ingredients have a history of safe cosmetic use.
