Thanks for writing to us.
You seem to have developed cheilitis
. It could have occured due to lip biting or picking of dry, lip licking, application of any lip balm or lip stick. Sometimes toothpaste or any nutritional deficiency
, infection too can induce such lesions.
To treat the same avoid lip licking. Do not try to remove dry dead skin. Apply a mild steroid
antibiotic cream for few days. Once the lesins heal use a lip balm with good sun protection factor.
Hope that helped.
