I find that I regularly use some form of ChapStick type product — mostly just as a moisturizer for my lips year-round, but also to heal dry, chapped lips in the winter.
I recently discovered Neosporin LT after seeing their commercial on TV.
Their tagline was something along the lines of: "You know how good Neosporin is for treating cuts and scrapes… Imagine what it could do for your lips."
