LOL, Country Girl,
I use an electric toothbrush!
Fact: Lips have no pores. So, we cannot really put anything on them that can "sink in," in anyway. All we can do for lips is to protect them with the best thing we can find.
My favorites are shea butter, (which is the cream most chosen by professional dancers to soften feet and legs and to keep them from being dry. It has to be good shea though...) or a Carmax or something... It really is about what you feel does the best for you and what will cover them with something protective and non-drying. No magic bullet.
Course, Country girl can tell us that we can sloth them off and make them smooth before we put that stuff on them!

You have no pores under your eyes either. Be gentle.

I'm full of silly trivia here.
