Re: sebaceous glands? What if the sebaceous glands in our lips don't produce sebum.

"From superficial to deep, the layers of the upper and lower lips include the epidermis, subcutaneous tissue, orbicularis oris muscle fibers, and mucosa. In cross-section, the superior and inferior labial arteries can be observed as they course between the orbicularis muscle fibers and the mucosa. The vermilion is composed of nonkeratinized squamous epithelium that covers numerous capillaries, which give the vermilion its characteristic color. Numerous minor salivary glands can be observed on a histological section of the lip. Hair follicles and sebaceous glands are located throughout the lip skin; however, these structures are absent in the vermilion."

 My fault for not being specific.  I was referring to the vermilion portion of the lip because in my case that's what was peeling.  Occasionally extending across the vermilion border to my face.
