This could be a part of Cheilitis, which is a medical condition involving inflammation of the lip. Or a bad case of chapped lips
, a condition whereby the lips
become dry and possibly cracked. It may
be caused by the evaporation of moisture.
Lip balm can often provide temporary relief, though it should not be used extensively. One should avoid licking their lips
as saliva contains the enzyme amylase, which can damage the already compromised lip tissue.
