The Nue. Co Barrier Culture Moisturizer does more than just hydrate the skin. Using patented technology, it also protects and repairs the skin's natural barrier that defends against pollution, UV light, and infection. Its lightweight formula is infused with peptides, ceramides, prebiotics, probiotics, and postbiotics to boost collagen and elastin production while replenishing the topical microbiome and rebuilding the skin barrier. This helps lock in moisture, resulting in visibly plump, firm, hydrated skin. For the best results, use with The Nue Co. Barrier Culture Cleanser.
