If you are worried about dry, flaky lips, try this at night.

My lips tend to chap and bleed all year round, so I never even dreamed of wearing matte lipstick. Before going to bed, I apply a generous, thick layer of a rich lip balm or Vaseline right up to my lip line. When I wash my face the next morning, I gently rub my softened lips with my fingers, and the dead skin cells slough off smoothly like dead skin. Since I don't have to forcibly pick at them, I don't get any cuts, and my makeup applies incredibly smoothly.
