I'm not sure if cocobutter does much for them but a product I used on my stretchies was called Bio Oil. Its available on the shelves in supermarkets and pharmacies.
Its pretty greasy, so you have to wait for it to soak in before getting dressed otherwise it will stain your clothes. And its a little more expensive than coco butter, but it worked like a charm. However this was when my stretch marks were still in the early stages...like Evangelina said.
Its also good for acne scarring and uneven skintone.
