Ceramide NP, Cholesterol, and Sphingolipids form the skin barrier's structural matrix to replenish what the barrier loses and reduce transepidermal water loss, paired with Phytosphingosine, Hydrogenated Lecithin, and Glycolipids to reinforce the lipid bilayer structure. Dual molecular weight Hyaluronic Acid (Sodium Hyaluronate + Hyaluronic Acid) delivers layered hydration from deeper layers to the surface, while Panthenol draws moisture in and calms redness and irritation. Beta-Glucan rounds out the formula by soothing inflammation and supporting barrier repair.
