Tammy, I LOVE the Sun Smart!! We used this sunscreen on a family holiday this week. We were at the Calgary Zoo on Monday, and it was very hot & sunny. I shook the bottle really well before using it. I loved how easy it was to apply!! It was very effective for both me & my children. I forgot to apply it to the back of my neck, and my neck got sunburned. My arms & legs & face did not! Very, very happy with this product!!
