Stretch Mark Creams??
I personally havent used this, but my best friend has and swears by it. her marks have faded from the brighter pink purple to whiten out, and the older ones arent so deep. Its called a Derma Roller, you can get them on amazong, they are about 30 bucks, its a wheel with little spike like things (its siupossed to breaks down and massages the scar tissue and lessens the harh appreaence)
I've had nasty stretchmarks since my growth spurt as a little kid, and I've used everything! Mederma did not work for my scars OR my stretchmarks, anymore than a regular lotion would. Same with cocoa butter. The one cream that really does work, but it also very pricy, is Strivectin. I LOVE that stuff!
