Super light and doesn't come off with sweat
Style: Tropical Coconut
Great stuff. Its super light, once the smell wears away you forget you every applied sunscreen. It also goes on super easily and doesn't leave my face super shiny. To my surprise it also doesn't come off easily with sweat. I've used other brands and the moment you sweat it just all washes away. Overall great stuff. The fragrance is a bit strong for me but I usually use unscented stuff so I'm extra sensitive to it. Good thing is the smell does wear away after a little bit.

This sunscreen body lotion is quite nice.
Style: Piña Colada
This sunscreen body lotion seems to work well. SPF 30 is the highest I could find with moisturizing capabilities. The smell is a bit overwhelming when you first put it on but it then goes away... so why the added scent. I wish it were SPF 50 and unscented. Otherwise I would have given it 5 stars.
