Hi I used to peel the dust on my outer ear flap, it became a wound with a black layer clearly visible in that area, also a small pus will be formed and once it is dried I will pull it.and again it forms..and it is reoccurring. I am shyed to go in public places due to this mark on my ear which is clearly visible. Its my mistake to stop my itching sensation and try to revisit that spot every week. Please suggest good skin oibtment that restores my skin from that black layer and also the wound.
