Yes, it leaves a white cast, but it isn’t as thick and sticky as most out there. Very few ingredients makes me happy. I’ve tried mineral sunscreens with all zinc and they feel smothering, and like velvet everything sticks to the face. This one, with smaller amounts of zinc and titanium is better. It will pill if you use too much and rub too vigorously.

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.
