Welcome to HCM.
YOUR PROBLEM MAY BE DUE TO Soap or face powder allergy. Sometimes excessive licking habit of lips of dribbling of saliva also may be a reason. If you have such a habit try to avoid the same.
Use gentle soaps containing moisturizers or syndet bars. Baby powder
is better if you want to use face powder.
YOU use steroid
cream along with some vitamin tablets containing Vitamin A
after consult with your dermatologist
. Greens, carrots, bananas, fish are good source of Vitamin A.
Get well soon.
