Doesn't cause acne! And MAY work for you.
I'm using it now and I like it enough to use it for as long as I need to. I think it helps a bit. But scars are hard to fix. Even my derma said that nothing short of laser surgery will help...and even then, the laser will just improve the appearance...it still won't be perfection.
Try mederma. I recommend it. It doesn't cause acne. It was recommended by my derma.
