ACU MOIST is a moisture occluding lotion ideally suited for anyone experiencing over drying of the skin caused by acne treatments or persons looking for a non-oily light skin moisture occluding crème. ACU MOIST is rich in essential fatty acids that are needed to keep your skin healthy. Vitamin A acts as a protective barrier to prevent water from leaving your skin. ACU MOIST uses Dimethicone which is a type of silicone oil. Dimethicones are unmodified silicone oils. Silicone oils stay on the surface of the skin as the molecules are too large to penetrate deeply into the skin. Because it stays on the surface of the skin, dimethicone provides a skin barrier that prevents transdermal water loss. This is an excellent ingredient for someone whose skin barrier has been disrupted or whose skin barrier is seriously compromised. Soothing and comforting, calming and healing, anti-inflammatory and reduces redness. Vitamin B5 stabilizes the skin barrier function, reducing the amount of water lost through the skin. It also contains antimicrobial properties that are crucial to controlling the growth and spread of bacteria. It rebalances oil production. Vitamin B5 increases Coenzyme A that is involved in the metabolism and the break-down of sebum. An effective pH regulator ensures that natural skin care products remain in the optimally acidic range of pH4.6-5, at which skin thrives.
