Turn back the clock. Known as the "gold standard" in reducing fine lines, the drug Renova is the only prescription cream approved to treat fine wrinkles, hyper-pigmentation and rough facial skin -- and it works while you're asleep. For a nonprescription alternative, you may want to try Dr. Murad's products, which contain retinol to help encourage healthy cell turnover, reversing damage that may have occurred during the day.

Nighttime Hydrating. Night creams containing olive oil, vitamin C, as well as gels containing plant enzymes and essential oils are excellent for moisturizing and helping repair skin damage while you dream away. Make sure you use products that are non-comedogenic, especially if you have oily skin. DermAlive makes a nighttime hydrating nutrient gel with myrrh, sandalwood and lavender.

Exfoliate your skin. Skin that looks "old" or "sallow" may be easily rejuvenated by removing patches of dead cells from the skin's surface. Alpha-hydroxy acids, or AHAs, work by dissolving the glue that holds dead cells to your skin. Unless otherwise stated, it may be best to use these products at night because they can actually make your skin more sensitive to sun exposure. Look for the words glycolic acid on the label in such products as Murad and Aqua Glycolic.
