<s>[INST] The skin on my face and neck is extremely darker than the rest of my body and is very noticeable, and it just happened in the last 2 years. What caused it and how can I get the skin on my neck and face to be the same complexion as the rest of my body? Some background information, in the last 3 years, I gained a lot of weight also, and now I am eating healthier, and I also am starting to be on a daily skin care regimen (I m 15, and I don t have any acne yet) but I really want to lighten up the skin on my face and neck because it s extremely noticeable and I hate it. Also, a few weeks ago I was sick with a cold and the tip of my top lip swelled up and bumps started forming around them, the bumps are gone, and the swelling went down, but now there is a very noticeable dark line where the bumps were, and I wanted to fade that too because it looks like I have a mustache and I don t. Please help me. [/INST] Hi There, Please upload some pictures and should be able to help. Regards Dr.Sasi Attili Consultant Dermatologist www.onlineskinspecialist.com </s>
