HOW CAN I FADE STRETCH MARKS?

i have just a few little pinkish stretch marks. they dont look too bad but i want them gone. i have tried cocoa er, vitamin e, palmers and mama mio. and nothing has worked. i have been tanning and that has helped but i dont want to keep tanning. so i was thinking about maderma or maybe apothederm. or maybe something else. what actually works???
