Chapped lips?

thats happened to me not only when its cold but also when its summer and my lips get dry dry dry and i lick them and bite them and then start ripping... i read in a magazine to brush them with a toothbrush or your towel and put on the chap stick or other i use carmax ( i love it) or you can use something for broken skin like neusporin. i dont know how long it would take to heal though.
