Yes, you do! There is a cream ( I forgot the name) that

you need the dr. perscription. Without the cream, obagi will not work well. Obagi has some medicine inside, it basically works as getting rid of the old dull skin, and allows the new skin to surface. So you need a dr. to see you and give you it. But the dr. you find has to be a physician that sells obagi. You can find the dr. list on obagi.com web site.
