I'm using retin-a micro to help with my shallow acne scars. I've been on it for the past couple weeks, and I see a slight improvement. I use it 4X a week at night and Olay Regenerist Night Resurfacing Elixir 2X a week and one "off" night. I'm currently using Neutrogena Fresh Foaming Cleanser morning and night, and I'm not sure if that's too harsh to be using while on these products. I have oily, but not TOO oily skin and use Olay Regenerist Face Moisturizer SPF 15 during the day.
