Great sunscreen, but too pricey!
Size: 5 Fl Oz (Pack of 1)
I love COOLA products. They are a good substitute for my favorite sunscreens by Bare Republic - which was discontinued. Unfortunately COOLA products are very pricey. For that reason, I must use other brands where it makes sense. Trader Joe's spray sunscreen works very well and is $5.99. Coppertone Water Babies works for water sports. I'm saving my $28 COOLA lotion sunscreen for when I need a non greasy odor-free sunscreen, for example when I spend time in the sun followed by lunch out or shopping.

Would recommend this sunblock!
Size: 5 Fl Oz (Pack of 1)
Loved this sunblock for my stay abroad in the Caribbean. Left no white cast, and barely had any sunblock smell. Felt like a lotion if anything, and best of all, I didn't get burned! Would recommend.

It works
Size: 1.7 Fl Oz (Pack of 1)
I invested in this for its travel size and my needs for a product that would protect my skin and not make it feel super oily. This delivers!!! I used it for a week in Florida with UV up to 11 on some days and didn't face a single issue, even after a Disney day. I was almost in disbelief at how lightweight this product is for it to work properly, but the protection strength is fabulous. I don't burn in the sun, but if I do, its typically along my face where the bridge of my nose is or my upper cheeks. This product basically said, "not today, sun." Bonus, it didnt burn or sting my eyes all day in Disney parks heat, and I didn't need to reapply even though I brought it just in case. Maybe it was the product or the Disney magic, but my skin also didn't look oily or shiny at all in my pictures with the product offering a nice matte finish.
