The amount of peeling is also related to how much peeling needs to get done! The idea is to remove all the dead top layers of skin which, as you get older, build up more and more. So, if you're younger, there's not as much peeling to be done. I was pretty shocked by how much dead stuff had built up on my face. I've been confused at the six month point, though, as to how much of the retinol to use (I'm at the six month mark) on a daily basis. I didn't know that part about no moisturizer - the doctor where I got the system did not explain as well. So, thanks.
