Really impressed!
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
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.

Funny after taste
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
Usually love Hawaiian Tropic products but this lip balm has a weird taste. The spf is good, if you don't mind the taste.

Hawaiian Tropics highly recommended for sensitive skin.
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
Love this product. This is my first summer using it. I was not disappointed. I have super sensitive skin, and can’t use most products. One thing I did notice was a few times I would get a small pimple or blackhead along the lip line. The dermatologist said it was clogged pores, but no reason not to continue using it. I have tried a few other brands and had more breakouts/ blackheads. So I keep going back to Hawaiian Tropics.
