You can buy vitamin e gel capsules and break them open, then rub them over your stretch marks. Vitamin E is like a skin miracle...my brother even used it for stretch marks from weight lifting and it literally erased his. I have used vitamin e on my face (to prevent crows feet and fine lines) and legs and been so suprised by the results. The really good news is that it is really inexpensive. Try Walgreen's or any local drug store...
Good Luck
