i have tried trilastin although it wasn't after pregnancy...i'm only 17! lol i have stretch marks on my breasts and trilastin has worked very well for me i've been using it for just about 2 months now and you can barely see my marks anymore. i only had my marks for about 6 months and they were silvery white before i started using it so they were farely new still. but it's been working for me and i'll continue to use it. i'm hoping since i'm young that i can get rid of my marks completely. but who knows i don't want to get my hopes up too much. but i have seen terrific results so far. i would recomend it to anyone. i hope this helps! good luck!
