Works by the Skin Trios: Repair, Restore, and Retain. Formulated with skin-identical phytosphingosine-based ceramides, cholesterol, and free fatty acids, it fills the gaps between corneocytes to repair the disrupted lipid bilayer structure. Phytosphingosine also acts as a biological precursor, stimulating the skin to restore own ceramide production. An ideal moisturizer, providing lasting hydration and relief from dryness associated with dermatitis.
