It seems you have Exfoliative cheilitis
...you did not mention when you had herpes
simples and which site( whether it was herpes labialis?) treatment has to be accordingly..anyway try
1. Take plenty of fluid everday.
2.Cap Zavit one cap every day
3.Elovera IMF cream 3-4 time a day local application
4.If you had not herpes labialis then try Crolim .1% oint once day...
hope this will work..ll take time.
