Hi! I'm of african(ethnic) origin. I have a slight concern. Over the past 8-10months,my lower lip has developed some discolouration. I have brownish going to maroonish lips. Now those spots are a much lighter shade. Some guy asked me if I drink gin too much,cause it appearantly burns the lips. But I don't drink gin. I do smoke but not that much. What's wrong and is it something I can reverse? And how? Thanks...
