70 yrs old and love Obagi

Hi
I’m 70 yrs old. I’ve always taken care of my skin since I was a teenager. Two years ago i started the Obagi Nu- Derm system with tretinoin every day for three months. At one point I was worried as my skin looked worse. My skin peeled every day bit by bit and wrinkles looked worse. I was advised to keep on with the treatment and I did. I’m happy with the results. I didn’t do a maintenance course over this past two years but have decided to do another course again and thereafter a maintenance course.
