I'm 22 and dark skinned. For the past 10 years or more, I have been experiencing a chicken like skin patch below my chin and jaw. It's really annoying and unpleasant. As this wasn't enough, I also have discoloration on that area, like darker and dry. Sometimes I get some acne there. It's not like I have not tried to treat this. I went to two different dermatologist twice, when I was young and their prescribed things didn't work. What should I do now? Should I consider grafting?
