Great sunscreen
Size: 5 Fl Oz (Pack of 1)
I love this sunscreen and I even use it on my face. Good value in a large size container.

One of the few body sunscreens that doesn't trigger my sensory issues
Size: 5 Fl Oz (Pack of 1)
I have sensory sensitivities, so wearing sunscreen is usually a pretty unpleasant experience for me. I can't stand heavy textures, greasy finishes, or that sticky sunscreen feeling that seems to sit on top of the skin all day. I'm also bothered by mineral and matte sunscreens that dry my skin out. It's very hard to find a sunscreen as genuinely comfortable as this one is.
I bought the Coola Sunblock Body Lotion because several reviews mentioned that it actually feels like a regular lotion once applied, but I honestly assumed it still wouldn't work for me.
I was genuinely shocked the first time I used this. The texture feels silky and lightweight, absorbs quickly, and leaves my skin feeling soft rather than coated or oily. It really does wear more like a comfortable body lotion than a traditional sunscreen, and I don't notice any residue or oily feel at all, which is amazing.
I also love that it's fragrance-free, which makes it even easier for me to tolerate, especially with sensitive skin and sensory issues.
Coola Sunblock Body Lotion is one of the very few body sunscreens I've tried that I actually enjoy wearing, and it works perfectly. I am very fair and burn easily, but I had no burning or redness on my first outside day of the summer while wearing this.
It's sunscreen that works and that I can actually wear with zero discomfort. Amazing.

Love the quality!
Size: 5 Fl Oz (Pack of 1)
Im 63, with fair and sensitive skin. I love this high strength sunscreen that isn't greasy and doesn't have added ingredients and perfumes that bother me and make me break out.

Expensive, but worth it
Size: 5 Fl Oz (Pack of 1)
What's the best sunscreen? The sunscreen you'll use consistently. I like Coola because it feels like moisturizer, not sticky gross sunscreen. It's pricey, but I think you get what you pay for with Coola.

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.
