I have a bunch of stretch marks. Coco butter doesn't work. Had them for long a time like for years... Weigh 105 to 110 height 5'1. What can I do?

Mederma stretch mark. There is specialmederma for stretch marks, not for s ars. Thiswprks only on fresh red stretch marks. See answer re carboxytgerapy and laser.
Mederma. Mederma is a scar reduction gel. Sometimes it works on old established scars. It can be pricey, but you try it for 6 weeks and see for yourself. It is located in the bandaid aisle in the drug store.
