I use this brand as my daily body sunscreen and love the smell, so I was tempted to buy this lip balm. I'm so glad I did! It smells great, and my absolute favorite thing about it is that it seems to last all day. I wear it with a light lip liner and my lips stay soft and moisturized after a long work day, 2 meals, etc. It does have a bad taste, but not nearly as bad as other brands I've tried. If you do the lip stick trick with your finger its unlikely to get in your mouth, unless you bite your lips. So its been a great protection against lip biting as well.
