Karin Herzog Vita-Kombi 1 ,1% Oxygen,the perfect delivery of oxygen, water, and vitamins A and E for normal, combination, sensitive or dry skin. For skin to function properly, it must have an adequate supply of oxygen. Over the years, the amount of oxygen reaching the skin from the blood decreases. Without adequate oxygen, the skin does not breathe properly, and begins to appear dull and lifeless. Because of the unique stabilization process of oxygen in the KARIN HERZOG VITA-A-KOMBI products, oxygen is literally pressed into the skin as it changes from liquid into a gas upon application. The rush of oxygen - which helps deliver the water contained in the VITA-A-KOMBI emulsion for instant hydration - provokes a "micro-massage" which can stimulate blood circulation, allowing the skin cells to function more effectively, receive more nutrients, achieve their proper balance - no matter what your skin type. For the first two weeks, apply a thin film at night after cleansing. After two weeks use twice a day morning and night. For those with oily skin, and large pores; after the first jar, to increase effectiveness, you may change to Vita-A-Kombi 2. Wait 5 to 7 minutes before applying any cream on top of VITA-A-KOMBI.
