Apply an antioxidant under a moisturizer before bed every night to repair damage from the day. (Don't forget your neck, chest, shoulders, and the backs of your hands all of which are exposed to the sun on a daily basis.) If you're using Retin-A, you should apply the antioxidant first, then the Retin-A and lastly, a moisturizer. And, since many sunscreens don't have antioxidants in them, you should always apply an antioxidant under sunscreen before you go out in the sun.
If you have drier skin, it is important to remember to layer a moisturizer over your Replere rejuvenating products for extra moisture needs.
