Not sure I understand the blue light feature of this, but I love how this feels during a hot day! I usually carry this when I go to the pool with the kids and use it to reapply after getting out of the water and watching them from the pool deck. I burn fairly easily and haven't burned using this, leading me to believe that it functions well. I like the smell and I like the cooling mist on hot summer days! One quibble, it does leak if not tightened carefully!

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.
