Used in skincare formulations for its anti-aging properties, particularly in reducing the appearance of fine lines and improving skin elasticity. It supports skin barrier function by enhancing moisture retention and is often included in creams and serums targeting mature or sensitive skin. Its chiral (R) form is preferred for better biocompatibility and metabolic activity in dermal applications. Also investigated for use in lipid-based drug delivery systems due to its structural role in bioactive lipids.
