I'm suffering lesions on my lips for over 2 years. They come and go every 2 weeks. What I understood is this is some kind of cold sore because a) it itches b) puss filled blisters which later turn into scabs. When they leave, my lips are dehydrated and always need some kind of moisturiser. I've consulted dermatologist before and he prescribed me picon cream/ mupi ointment/ alorti and kineto tablets. They cleared the lesion for a while but they come back. Especially if it's cold. I have stopped using lipstick and I don't smoke. Kindly advise me what should I do to keep this condition at bay. Thanks.
