I am a lip balm junkie. At any given time, I have two or three on hand. Burt's Bees has some of the best lip balm around. I am a fan of their original lip balm, but I switched it up and went with the Ultra Nourishing lip balm for some added moisture. This balm has Kokum Butter and claims to provide 4 hour moisture. That being said, I have to admit that I found this balm pretty disappointing. When first applied, it feels amazing and you think that it will live up to the 4 hour claim. Sadly, the initial amazingness is short lived. After 15-20 minutes, my lips begin to dry out again and sometimes they begin to peel a little. This balm is 100% natural and hypoallergenic.
If you have sensitive lips, I would probably stay away from this balm just to be safe. I haven't had any issues with burning or redness, but the peeling is a little annoying. I would just stick with their original balm. You cannot beat that.
