The original surface hydrator. Natural Moisturizing Factors + HA is a moisturizer that works with your skin to support its natural hydration barrier. By using a collection of ingredients that appear naturally in your skin—such as amino acids, fatty acids, triglycerides, urea, ceramides, phospholipids, glycerine, saccharides, sodium PCA, and hyaluronic acid—this cream keeps the outer layer of your skin protected and wellhydrated, without feeling greasy. Plus, it provides both immediate and lasting effects, as it works to significantly improve skin barrier function with regular use. Use as the last step of your skincare routine as a moisturizer.
