Eliminating acne with solutions designed to reduce excess oil and dry out pimples can leave your skin feeling dry, chappedand tight. This glycerin-rich moisturizer, a part of the Obagi CLENZIderm system, corrects any drying affects. A smooth and supple complexion is achievable with glycerin that attracts moisture to the topmost layer of the skin. Once glycerin is set, dimethicone then lays a protective barrier to prevent that moisture loss. Supplement your skin daily with this skin protecting moisturizer.
