Cholesteryl Succinate

The succinate half-ester of cholesterol. Cholesterol is a critical structural component of the skin's lamellar lipid bilayers, maintaining fluidity and barrier integrity. The succinate modification improves water dispersibility compared to free cholesterol, enabling its use in O/W emulsion systems. Commonly included in ceramide-complex formulas alongside Ceramide NP and free fatty acids for a multi-component barrier repair effect.
