Happy to say that I finally received the Regimen in the mail today! I only purchased the treatment and the AHA because I already use cetaphil and cerave as my cleanser and moisturizer and am happy with the way they've been working. I know a lot of people say the treatment dries out their skin, but I put it on tonight and it actually made mine more moist (probably because the clinique stuff I've been using had dried out my skin like CRAZY) so I actually think the treatment is better for me.
I'm starting with a small amount of treatment and will work my way up. I think I'll wait until I'm about two weeks in with the treatment before I start the AHA.
