I only use it when my lips are chapped, but Kisstixx is fantastic! They come in two packs with great flavors. I have strawberry daiquiri and pina colada. When you kiss someone wearing one of the flavors, they make a new flavor. ;)
Best of all, it works really good. I use it whenever I feel my lips starting to get chapped. It repairs them, and I don't have to wear it all the time.
