Step 1: Cleanse and tone. Step 2: Apply Cellex-C Advanced-C Serum or Serum for Sensitive Skin. (If you are using Skin Tightening Cream apply Skin Hydration Complex first.) Step 3: Skin Hydration Complex Apply Skin Hydration Complex. (Avoid direct contact with eyes.) Step 4: Apply moisturizer. Note: This product begins its moisturizing work beneath the surface of your skin. It is not intended for surface hydration, so you must use an additional moisturizer. During the first two or three weeks, absorbency may be greater for some people than others. Begin by applying Skin Hydration Complex a little more generously for the first few weeks. Gradually you will notice that the skin no longer absorbs the fluid as quickly. This is a sign that your skin has restored much of its moisture balance. Once this happens, only a small amount of Skin Hydration Complex is required to maintain this as your skin will regulate the intake automatically.
