The Renewal Program is also good to help clear pores and to keep them from becoming clogged. Glycolic acid can lighten pigment marks in the first layer of skin but not usually age spots which are in deeper layers of the skin. After using these products your skin should look brighter, more supple and smoother.
It is better to use this at night as your skin may be more sensitive to the sun as the product is working to lift off the top layer of skin.
