Thanks for writing to us.
So you have traumatic cheilitis
of lips( chapped lips
due to lip licking and chewing). To treat the same, avoid lip licking or chewing. Apply a lip balm multiple times in a day. Apply a mild steroid
antibiotic cream like flutibact. Nadicin c contains a very potent steroid and is too strong to be used over lips.
Also take multivitamin
supplements for few days.
Hope this helped.
