Prevage MD was created by Allergan, Inc., the same company that developed Botox and Latisse. Free radical damage (caused by environmental stressors such as pollution, ozone, UV light and cigarette smoke) causes oxidative stress, which results in wrinkles, loss of skin elasticity and uneven skin tone. Prevage MD traps and neutralizes free radicals before they cause any damage. Also, existing wrinkles are reduced and the skin is made smoother and tighter.
