Welcome and thanks for posting your query on HCM.
As per your query you have itchy, chapped lips
with red sore spots and scarring.
You have not mentioned in your query about your age and since how long you have these problems. Now there can be mutiple reason for chapped lips but most commonly there are two important reason: - contact dermatitis
with any chemicals and the "self licking" process. Both of these can coexist together.
Just check for the things coming in the contact of the lips as well as stop licking the lips. Drink lot of water and increase fruits intake. Hope these informations are helpful. If you have any further query I will be happy to help.
Wish you good health,
