lip-licker’s dermatitis
n.— «When you lick your lips, the temporary moisture evaporates, leaving the lips further dehydrated. Too much moisture around the lips can sometimes lead to what’s commonly called lip-licker’s dermatitis—a rash that develops around the mouth from too much licking. Next time you get the urge to lick apply a lip balm instead.» —“Keep lips from getting chapped this wiinter” by Jennifer Dean Press-Enterprise (Riverside, California) Dec. 17, 2007.
