Got burned
Our son used up the entire bottle during a day at the beach, reapplying every 1-2 hours, and still got quite burned.

Im a ginger. I know sunscreen and most make me sick from being too thick and clog my skin... but this is golden. Smells great. Feels great and I even get freckles and tan wearing it.

Can't beat the 8 ounce sprays.
Size: 16 Ounce (Pack of 1), Style: SPF 50
Fantastic product. The scent is great, and the sun protection excellent. But the best thing is the fact that each of the two sprays contain 8 ounces of product for a total of 16 ounces at a very reasonable price.
