I wish I had a dermaroller a few years ago, to use on the face like in this video http://weightloss-stories.com/dermaroller-acne-scar-removal-2 . This is a great tool to remove acne scars fast and be free of acne scars fast and easier that you ever thought. I wil buy a derma roller almost for free here: http://amazon.com/gp/product/B00K0UF92O, because it costs only 15 dollars.
