I am almost done with the 12 week trial and I started peeling again this week :/ Random. But I am feeling good. I purchased some C serum from Obagi and it is on it's way to me. I will update my routine and let you know what I notice while using the serum. I am almost out of #3 and #2 so I had to buy some more of that. It will probably last another 2-3 weeks so that is pretty good. The #3 was expensive :( $80, but I think it is worth it.
