I have always picked my spots, leaving behind horrible red marks, (Lucky I don't get ice pick scarring, etc) and I have kind of gotten sick of how bad my skin is, how every cream or product I put on my face stops working after a while, so I decided, I would stop picking my spots, let them dry themselves out and then deal with the scaring, so I left one or two go away on their own, and they still left scars! Should they not leave scars if I leave them alone, or is there anything i can do to prevent it?
