Hello, I am new to this forum and looking for answers. I just noticed from about a week ago, my skin in my hand (above index finger & middle finger mostly) is darker than my normal skin color. It's like blackish actually. It burns. Can this be caused form dry skin? I have noticed that my hands have been extra extra dry. Dry to a point where I had "cuts" in them and caused burning. It is still burning now. Not sure if this something that is caused from skin being too dry? Please advice. Thank you
