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

I think some cases are basically eczema/psoriasis, but there are many things that can cause peeling lips. There's no one cause and no single cure.

I beat it with L-lysine & stress formula B-vitamin supplements. It's helped some people and not others. I do agree that you can't let it ruin your life. Stress can make it worse.

Remember, most people are too caught up in their own insecurities to really notice what we obsess over.
