I've been using dermystique products for about 3 years now. My skin has improved dramatically. Before finding dermystique, I've tried different type of acne product brands such as obagi , it didn't work and it was too harsh for my skin. Dermystique is mild, good for sensitive skin and the best part is .. it actually clear my skin. This product was developed by Dr. Brent Moelleken, a plastic surgeon from Beverly Hills . Dr. Brent has been featured in magazines and Discovery channel's "Extreme Make Over"
