I am 48 and have been using the Obagi Nu-Derm line for 12 months. Prior to that I used Cellex C and Estee Lauder skin care products. I like Obagi but am having difficulty finding a good maintenance plan - it seems that now the flakiness has subsided which only occurred in the first few months, I just stay a little red - especially if I use the Blender and Retin A every night. If anyone has advice on how to use Obagi for the long-term or is using it along with another line, I am interested. I miss using a moisturizer and it seems that at times, I feel like a need a good mask to pull out what feels like are little bumps below the surface - by the next day, this feeling is gone. As noted earlier, I like Obagi and it definitely works at the cellular level, but there are days when I am not as pleased...
