Hi there, I m 16 years old and a female. My lips have started to turn dark, itchy, and began to burn like the end of Feb, towards March. The weather has been changing from cold to hot over and over and I m guess my lips got irritated or something. Now my lips are completely black and I have dark spots on the bottom of my lips. I tried putting vasaline but the color and the spots arent going away, and my lips burn after the vasaline wears off. I m worried that I may have something serious since dark lips indicate cancer or another serious disease. Is is cause of hormones or something more serious?
