The Obaji Nu Derm system is good for evening out skin tones, discolorations, etc. I had moderate acne for about 10 years along with a few cysts. Obaji has cleared up the discolorations and smoothed out my skin. Obaji also incorporates Retin-A, so I would ask your doctor about using this program. Also, they have a wonderful medium depth peel called a Blue Peel. I have had two.
One piece of advice. You can order this system over the internet. But my strong advice is to go to a doctor's office that carries this line so that you can get the appropriate instructions and followups. Also, they will have to apply your blue peel if you decide to have it done at some point. I am under the care of a cosmetic surgeon for this program, but many dermatologists also offer it.
One more thing....the program seems expensive in the beginning. I am living on a secretary's salary and I think my first purchase for the starting system was around $450. But I have found that it is no more expensive in the long run (you will use less of the product when you get to the maintenance stage) than the products I was purchasing at the Lancome counter and all those other products that said they worked and then they didn't. By the way, I have been using Obaji for 4 years now and I love it...it is so wonderful to get compliments on your skin.
