I am thinking about adding some glycolic peels to my treatment list. As I already offer microdermabrasion, which can work deeper into the epidermis, I just wanted to know if there would be any additional benefit to me offering similar treatments. I have done some research a notice that some salons offer both during one treatment. As a skin care therapist I can only use a peel of up to 40%, of course anything higher has to be carried out by a nurse/doctor. Is a 40% glycolic peel equivalent to a moderate microdermbrasion level?
