Obagi NuDerm pricey and time consuming, but VERY effective. I think almost every woman has something that they don't like about her skin. Some are concerned with wrinkels, fine lines, dry skin, oily skin, sensitive skin or break-outs. My biggest concern has always been "age" spots or sun spots. They tend to run in my family. Almost all the women in my family over 40 have them to some extent. My mother and I actually both have one on our left cheeks that are almost identical! I asked my dermatologist about what I could do about them. He told me that he had lots of patients who have had very good success with Obagi products. I have tried many over-the counter drug store. It is a little expensive. And it does take some commitment of time to follow the daily routine. But it definitely does the trick! I saw a very noticeable after about 10 to 12 weeks. I used to cover the bigger and darker spots with concealer under my foundation every day! But now, just a dab of foundation completely covers them. I am very happy with the results!
