The barrier is the skin's first line of defense against environmental hazards. The Nue Co. Barrier Culture Skin Care works to repair and protect the barrier for a healthy, balanced complexion. The two-step system includes the Nue Co. Barrier Culture Cleanser and The Nue. Co Barrier Culture Moisturizer, and when used together, their patented technology gently cleanses and nourishes skin, while replenishing the topical microbiome that protects against pollution, UV light, and infection. The result is fewer breakouts, decreased sensitivity, and balanced, hydrated skin.
