Talk to Dermatologist on The Protective Upper Layer Of My Lip Keeps Coming Off Again And Again In The Morning.

The upper protective layer of my lower lip comes off automatically every morning, revealing a red layer underneath. It's a bit painful and uncomfortable. I have consulted several top dermatologists in Lahore and undergone various tests, but my problem remains unresolved. I've used steroids, eczema-related ointments like Eczemus and Advantan fatty ointment, and allergy medications, but the issue persists. Could you please recommend an authentic doctor who can help me strengthen the protective layer of my lips to prevent breakage? I have also tried many good lip products (petroleum jelly, Aquaphor, La Roche, etc.), but nothing has worked so far.
