Did not protect
Size: 3.4 Fl Oz (Pack of 1), Style: SPF 50
Product smells great and goes on better than most mineral sunscreens. It was labeled as "reef safe" so I assumed it would work well in water. It did not. After just a half hour in the Caribbean water, my skin was red. The product did not say "waterproof" so we decided to use it only when we were away from the beach. Unfortunately, even in the cold spring weather of our northern climate we still ended up with red skin. We had no choice but to throw away the rest of the bottle. Do not expect this lotion to protect you from the damaging rays of the sun.

Great sport block for sensitive skin
Size: 3.4 Fl Oz (Pack of 1), Style: SPF 50
I use this whole playing tennis or pickleball, it might be a little much for everyday. Does not irritate my sensitive skin. Rich enough for dry skin. Very slightly white cast that quickly fades. Does not run or bother my eyes for sports. Basically perfect in all categories.
