Thanks for writing to us.
You basically have cheilitis
. This could occur due to frequent lip licking,sun induced inadequate hydration or nutrition,lack of moisture, dry weather and eczema etc.
firstly use a steroid cream to help the lesion heal. I would prefer fluticasone
for same. Apply till lesions are completely gone and then use a medicated lip balm with sun protection factor multiple times in a day. Avoid lip licking on picking at dry skin. Take adequate amount of water and good diet. Take multivitamin
supplements for few days.
Hope this helped
