I was given the AOS lip balm by a friend. WOW I used to use other products but my lips would stay chapped and I would keep applying the stuff over and over......with the AOS lip balm it actually healed my lips in a couple of days and I found that I did not need to keep re-applying this stuff over and over, in fact I stopped applying it after a week and I did not need to use it again for quite a while. I realize it is expensive, but you really don't go through it like the other lip balms out there...my only complaint would be that it feels like there are little tiny micro-beads in the stuff....but it does heal the lips up pretty fast.
