Any Successful Ways to Treat Keloids for 15 Year Olds?

Hi im 15, im a girl. i have two keloids. One on my left chest and left upperarm. they are about one inch long each. ever since august 2012 ive been getting injections. i recently had them lasered & injected. my left upperArm flattened out, but its still pink. Very noticable. the one on my chest is painful and itchy all the time. it dosent respond to anything . i dont want to have to deal with this my whole life. i get very selfconcious. Any other successful treatments i can try ?
