Sameproblem is right, lick away this white goo whenever it builds up and your lips will be in great shape throughout the day. However using your teeth will cause damage and rawness though. If your lips get too dry, use a lip balm. At night before you go to sleep, use whatever balm or jelly you like to put on. Pretty much normal lips if you do this.
Edit: Do not lick your lips when they feel dry, this will dry them out even more ;)
