What can I do?

So at the top of my lips there is a dark reddish line that looks like there’s peeled skin (you can’t really see the peeled skin the pic tho) it burns really bad so I tried to put chapstick on but it made it burn so much worse. I’m assuming it’s just badly chapped, but can I do anything to help ease the burn? Or should I just leave it alone and let heal on its own.
