Can a dermatologist write you a prescription of a face moisturizer? For example, if you have dark spots on your skin, can a dermatologist write you a prescription of olay 7 in one (a moisturizer)? Or do you have to get it by yourself from a store? Can you go to a pharmacy and the pharmacist can see the paper the doctor wrote to you and give you this product(the moisturizer) like any other medicines?
