This formula mimics one-half of the acid mantle: sweat, the secretion of the sudoriferous gland. Perspiration is responsible for thermoregulation and barrier function. Herb & Mineral is made with macerated soaked herbs and contains amino acids, fatty acids, vitamins, minerals, antioxidants, humectants, and other beneficial phytochemical compounds. They combine to hydrate, replenish, repair, maintain healthy barrier function, and help DMK oils and creams permeate the skin.
