Mederma works, but it takes a while, there is this stuff that is supposed to be "BETTER THAN BOTOX" its called Strivectin i think its super expensive my mom had it at home so i stole it from her and took away the marks on my chest in like 3 1/2 weeks of use, burns when you rub it on though, so other than your ass being on fire for like 3 mins not a bad option..
