Funny after taste

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.
