This link discusses, in a professional way, some of the products out there nowadays. Those products are not simple "creams and lotions", they are specifically manufactured for better looking "skin", NOT for anything like faster mitosis. Simple creams and lotions have no effect in the dermis, or anywhere else for that matter. But that aside, I thought providing this link would be mildly interesting, if only because of the illustration.
