I want to share my own stretch marks.
The first photo, I was 153lbs (BMI of 30) and the picture was taken in June 2009. In the second one, I'm 139 (BMI of 27) and it was taken this October. I'm not sure if the vanishing stretch marks are a trick of light or not (I sure hope not) but if it's not a trick of the light, those marks SURE did fade over the last year or so. I don't know when I received those stretch marks to be honest, so I don't know how long I had them. I'm also only 21, so I'm sure that played a roll.
I did absolutely nothing as far as any lotions or maintenance goes.
I hope that gives you at least a little hope
