i'm only 17 and i have stretch marks on my breasts and i'm not even heavy i'm actually really tiny! needless to say my self esteem has been ruined also. on may 1st, i remember the exact day, i began using trilastin sr and i've gotta say it's really working! it's been about 35 days or so and already i see a difference. i'm hoping with continued use that they go away completely! but i don't want to get my hopes up too much. my stretch marks were in the silvery white stage when i began using it. it's kindof expensive, $80, but i feel it was totally worth it because it has been working. before i used it i went to many forums seeing peoples opinion on it and it was all positive except for one or two people and i was desperate so i gave it a shot and i'm happy i did! if you want to read up more about it go to ecresearchcorp.com. i hope this helps you! goodluck!
