oh oops, I mean to only lick your lips when you feel all that gross skin built up on them :)
Licking your lips because they feel dry just makes them dryier and dryier, licking them to remove build up doesnt dry my lips out at all, it does the opposite in fact :)
You cant be obsessive about it either. Just go about your day and when you notice that your lips feel like some skin has built up on them, lick them until they feel good again :) Im telling you this because it has helped me a great deal.
