Why are my lips turning black.? Before my top lip was brown and my bottom lip was pink and then out of no where I started getting blacknow spots on them and it s spreading, even on my inner bottom lip. I don t take any medications. I m a teenager I dont smoke. And the only lip product I have been using is e.o.s. lip balms witch I had no problem with because I have been using it without issue until now. But I often forget to put lip balm on when I go running and I have to lick my lips and I do wonder if this may have caused this. At this point I m lost and I have no idea of what s doing this to my lips and I just want to find out why. Because soon both lips look to both turNing fully black.
