Stretch marks.......................?

I will pay whatever it is I need to pay, I don't care..I just want them gone. I was overweight when I was 10-13,then I lost weight. I am nearly 19 now. I was skinny up untill I turned 17, then I put weight on again, but now I lost it again and I got some new stretch marks. I have old ones and newer ones, but they are almost white now.. I work out, I use cocoa er and shea er and rosehip oil and aloe vera. I use everything.. Now I want to look into surgery..I read microdermabration can help make stretch marks less noticable and laser surgery, how affective are these at removing the stretch marks? And is there anything else that can remove them?
