Hi,
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.
