I've heard good thinks about the it works cream. I'm gonna try some to fade mine in a couple months hopefully. vitamin e oil is for scarring so it's supposed to help as well. Palmers lotion is supposed to help keep them away as long as you are religious with it
Preventing them or treating them? I've used palmers body lotion this whole pregnancy, and so far no new stretch marks. As for getting rid of/hiding them, I haven't the faintest.
Break open vitamin e capsules and use that oil.
