Natural Moisturizing Factors + HA is an effective moisturizer designed to mimic the composition of your skin’s natural hydration system. Infused with a comprehensive blend of ingredients that are naturally present in the skin—such as amino acids, fatty acids, triglycerides, urea, ceramides, phospholipids, glycerin, saccharides, sodium PCA, and hyaluronic acid—this formulation keeps the outer layer of your skin well-hydrated and protected, without leaving a greasy residue.
