The skin on my upper arms used to be so smooth.. I have a habbit of picking at my arms when I feel they have little bumps.. The backside of my upper arms is not smooth and kinda of rough and bumpy. What can I do to get rid of the bumps.. I mean you can see the little spots on my arms. Is there some sort of herbal remedy or cream from the stores I can buy to get ride of the scars I got from picking at my arms to make them look smooth again?
