Hi there . I am 26 yr old indian female with dark skin. I have PI hyper pigmentation . I made advised by my dermatologist to use obagi new derm system . I have been advised by my dermatologist to use moisturizer ( cetaphil dam ) in morning . I use moisturizer at 7 and after bath I use the obagi system at around 11 . I have read lot of blog of several obagi users who were strictly advised against moisturizer, as using moisturizer delays the peeling effect . Please help I m confused
