Hi Dear,
Welcome to HCM.
UNDERSTANDING YOUR CONCERN.
Thanks for your query .The symptoms you describe in your query are pointing towards condition known as
chapped lips .There can be many reason that cause chapped lips (
cheilitis simplex) like licking ,picking(as in your case),rubbing ,extreme
cold and hot environment and dry weather and .This can also cause discoloration.
When we suck,lick or pick our lips we remove natural moist layer of lips formed by sebaceous glands on lips and they become dry and cracked.
I would suggest you to avoid sucking,licking ,picking and rubbing of lips,keep yourself hydrated by drinking lot of water,use humidifier at home,use lip balm with broad spectrum sunscreen, apply cocoa butter at night and start taking vitamin B complex supplement.
If condition persists for more then a week
consult dermatologist for proper evaluation and to rule out any other underlying disease .Doctor may prescribe
hydrocortisone ointment.
Hope your concern has been resolved.
Get well Soon.
Best Wishes,
Dr. Harry Maheshwari
