This invisible yet bilayer shield prevents trans-epidermal water loss, safeguarding the skin's natural moisture reservoir. It also helps fortify the skin's intrinsic barrier with the inclusion of Ceramide NP. This naturally occurring lipid, a fundamental building block of healthy skin, acts as the mortar between skin cells, securing the moisture barricade from within. This isn’t temporary hydration, Ceramide NP empowers the skin's own defenses through enhanced ceramide production, enabling lasting moisture retention long after the final application. Prodew 400 is a 50% aqueous solution made from natural, non-animal origin ingredients designed to act as an effective moisturizing agent and humectant for the skin. It contains Betaine (30%) to improve skin texture and help retain moisture by binding water to the skin. Sodium PCA (10%) is a natural humectant found in the skin that attracts and retains moisture. Last, Sorbitol (4.2%) is another humectant that draws moisture from the air.
