A greasy mess
SUPER greasy. I have dry skin and it was incredibly greasy for me. It didn’t dry down at all and felt like it sat/slid around on my face. Obviously goes on clear since it’s a chemical sunscreen. Vaseline gel-like texture in your hand and applies like a silicone barrier. That part makes a little sense since I think dimethicone is high on the ingredient list. Unscented and didn’t test under makeup. I wouldn’t recommend this to anyone and I don’t think I’d try it again, which is disappointing cause I was hopeful with this one after reading reviews! The glowing reviews versus my experience makes me think folks aren’t applying enough SPF to get adequate sun protection. I’m a skincare girlie so it’s always a half teaspoon for this face.

Works well, smells great, goes on easily
Sun protection factor: 15 Sun Protection Factor (SPF), Size: 6 Count (Pack of 2)
It smells good. It goes on easily with the spray bottle. It keeps me from burning while out biking. It's a good price. Overall, a very nice product that does what it should. We carry it in our bike packs and in the car when we know we'll be out in the sun all day. Doesn't feel heavy when sprayed on so it smooths over your skin very well. Keeps me from burning.

My favorite sunscreen!
Sun protection factor: 70 Sun Protection Factor (SPF), Size: 6 Ounce (Pack of 1)
I have been using Hawaiian Tropic sunscreen for years and absolutely love the smell. I wanted to try a spray version as I hate the feeling of oily hands after applying sunscreen. This version sprays on super evenly and has that same beachy smell as the lotion! It stays on for hours and doesn’t leave a sticky residue. My go to sunscreen! With such high SPF as well, this sunscreen truly cannot be best for the value.
