Lately, I have had a strange clear skin film arise on my lips, usually
after brushing my teeth, or kissing my girlfriend. My lips are not
chapped nor does it hurt when/during/after the skin is removed. It is
usually on my bottom lip. Lips are still smooth with no pain or
bleeding what is the cause of this strange lip
skin that peels off my lips and what are the cures?

Skin sheds every now and then. I don't can't imagine it to be anything
other than skin. Go to your local community university and ask if you
can look at it under a microscope.

It never happend before and now it is a daily occurance, im sure it is
skin, in fact, i am positive it is skin. The thing is, i cant seem to
find any rhyme or reason to it appearing. My girlfriend NEVER had it
before either, and now she has it as well. Strange thing is, she says
she only gets it when i am around her (she lives long distance).
