smells fresh without being overpowering
Sun protection factor: 30 Sun Protection Factor (SPF), Size: 6 Fl Oz (Pack of 1)
The spray makes it SO easy to apply, especially when you’re in a rush. No white cast, no heavy feeling—just a quick mist and you’re good to go.

Bees think you’re a flower
Sun protection factor: 30 Sun Protection Factor (SPF), Size: 6 Fl Oz (Pack of 1)
Works great and I love the smell. Unfortunately so do the bees. Every time I wear it, attracts bees and have to fight off yellowjackets

One of the best-rated consumer sunscreens
Sun protection factor: 30 Sun Protection Factor (SPF), Size: 6 Fl Oz (Pack of 1)
I tend to analyze, no, overanalyze nearly every purchase I make. Sunscreen is no different. In fact, I'd say its one of those things you really shouldn't slack on... i mean Afterall, it's protecting the largest human organ! All of my in-depth reviews indicate that this was one of the top sunscreens to purchase due to its overall efficacy and purity of chemicals used in it.
All of that said - I really enjoy using it. It smells absolutely fantastic and makes me feel like I'm on vacation even if I'm just a couple miles from home. The application is extremely air-light, non oily, and it doesn't even feel like I'm wearing it. It didn't stain my clothing or rub off on anything. The spray comes out pretty lightly, as in you won't empty half the bottle over a few moments of depressing the button. Fantastic sunscreen and I will absolutely keep purchasing this.
