Protection
Style: SPF 50
I love this product, especially my husband because it’s all-natural. It contains minerals that leave a slight white residue on the face. While it would be nice to have a clearer texture, it does a beautiful job of protecting you from the sun.

Great product
Size: 2 Fl Oz (Pack of 1)
Product works great and has a great scent to it. It even works well against the hot Mexican sunshine. Definitely recommend this product. And we're able to carry it in our carry-on suitcases when traveling.

Excellent quality
Size: 6 Fl Oz (Pack of 2)
I love the Coola brand, and this product does not disappoint. The scent is tropical and not fake-smelling, and I love that the coverage is a wide, fine mist. Because of the way it sprays, I don't have to spend extra time rubbing the product into my skin. I do wish it was cheaper, but it helps protect my skin from burning and it doesn't irritate my skin. Highly recommend!

Smells great and doesn’t mess up makeup
Size: 6 Fl Oz (Pack of 2)
Love this sunscreen. Smells great and doesn’t smear makeup! It is pricey but worth it for me since I am very sun sensitive and need to apply multiple times daily.
