Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have spreading rough edge on upper lip which could be due to due excessive licking of lips which remove the natural moist layer from the lips .Hence cracks starts appearing on the lips which further become prone to fungal infection. Now i would like to suggest you that use petroleum jelly , drink lots of water ,avoid to stay in dry environment for longer period . Avoid using creams containing high steroid content ,wash your face with mild soap twice a day and avoid licking your lips . Use lip balm which can be directly applied rather than if you use finger it will cause spreading of infection again and again whenever you will apply with finger. Visit dermatologist once if your symptoms keeps persisting and get it examined. Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
