I got those awful red stretch marks on my stomach too, the year I gained a bunch of weight.

They did fade when I lost a few pounds a year or so later and now they look as pale as my other ones. They seem to be getting less and less noticeable as my belly shrinks. I just use lots of ordinary moisturizer. Your skin is young and that is a benefit. I'm sure they will improve in appearance once you lose a few pounds.

Good luck!
