I have seen that some dark spots generated across the upper lipline area including the upper lip.So i decided to do a chemical peel that is tca 15% after peeling that has no effect at all so that i decided to do 25%.After the peeling those black spots faded and it seemed that i got my desired result.But during few days i noticed some dark brown spots have generated those areas, even seemed much worse.I think i have got permanent hyperpigmentation on that area.I am not sure wheather it is burned or not.Is there anyone who can help? I am really worried about it
