Hello doctors, I've never had nice legs. Since I was 12 I've had spider veins that look like bruises behind my knees and stretch marks. My question is, what are these new lines that are appearing on most of my body as I don't get a lot of sun. I can pull and stretch my skin off my body and my legs have developed cellulite and lots of horizontal lines in a few months. I am only 32 and my breasts, legs, stomach have also developed these lines. What can be done about this?
