I have been using only Obagi products for two years. I am a true believer in this product. My dermatologist first wanted me to try it and I was skeptical (mostly because it costs more than what you can buy at the drug store). However, within three weeks and a picture to prove it, my skin was looking better., I like the way serum makes my face feel soft and looks as if it is glowing. I combine it with the other Obagi Nu Derm System. This product is a must even if used by itself.
