Can cocoa butter or other drugstore treatments help with stretch marks?

Yes, other ideas too: Some try cocoa butter, shea butter and vitamin e but studies are murky whether these help. New stretch marks can benefit from application of tretinoin cream (unless pregnant) which is a prescription cream or gel and new marks also respond to pulsed laser therapy. Older stretch marks improve with use of microdermabrasion and excimer lasers. Glycolic acid peel helps both new and old stretch marks.
