My lips have turned black; what do I do? (Photos)
About a month ago my lips were very dry and I licked them for temporary relief. A week later, a dark spot appeared on my top lip. Now my lips have turned almost completely black! It's extremely embarrassing, and I don't know how to resolve this. I don't smoke, rarely drink, try to eat a balanced diet, and have minor eczema flare ups. See photos attached for details. I have scheduled a dermatologist appointment, but it's not until after the Holidays so any help is greatly appreciated.
