Great for sensitive skin
This was great to take on vacation. I went to Cancun and used this on my face. Never got burned. I have super sensitive skin and this didn’t cause any reactions. I’m also sensitive to smells and I don’t notice anything with this product. Will purchase again.

Buyer beware!
Awful! I sprayed my face with it and immediately felt my skin burning. I opened the bottle and noticed all that was in it was a yellowish fluid that smelled like straight rubbing alcohol. My face still has marks on it days later from whatever the substance was. I have used this brand before, and never experienced anything like this. The product was either years past expiration, or liquid was replaced with some kind of chemical.

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.
