I had this pimple on face a week ago. I applied Clearasil pads as well as some honey and another acne cream and eventually the skin around the pimple became dark brown (my ethnicity is Indian). I thought it could be a bruise so I then applied wound healing cream (Arnica) and continued to use the Clearasil pads for another 2 days but then the skin around the acne could be peeled off, to reveal the pink flesh underneath. I continued to apply the wound healing cream and Clearasil pads but now, a couple of days later, the skin is turning dark brown again. What's happening?
