I have pretty horrible acne scars. I`ve been really curious about this derma roller. I mean it`s a bargain if it works. It retails for about $20. It was even on the talk show "The Doctors." It`s so scary though. I watched some Youtube videos on it and it seems pretty barbaric. What it does is that it has tons of tiny needles that you roll over your skin everyday and the needles prick your skin in a pattern. In essence, you`re reinjuring your skin so it will regenerate collagen while rehealing in a smoother form as oppose to pit marks. I don`t think I could do it but I find it interesting. I heard you get pretty bloody from it and sometimes bruise...yikes!
