Best facial sunscreen I have used
Coola makes the best facial sunscreen, and I have tried many brands previous to using Coola. The texture is light and creamy without being oily, absorbing well and leaving no white residue. It does not clog my pores and nor cause those white bumps that last for months. Coola sunscreen works well to protect my skin from sunburn and from making more freckles and dark spots. It has no perfumy fragrance, much to my relief. Once it has dried, I can apply concealer or powder over it. No oily streaks or caking of other make-up so I have no excuse to avoid wearing this sunscreen every day. I have recommended Coola facial sunscreen to my friends who had laser dermabrasion. Their skin is more sensitive to both perfumed chemicals and sun exposure, and they have given good reports too.

Pricey, but worth it.
Coola products were included in a swag bag for a work vacation at a resort & I’ve not looked back. (The smell of the body spray sunscreen made me wish I could eat it, tbh.) This product has become my daily sunscreen as it’s the only one I’ve tried that doesn’t cause my skin to break out. I love the natural ingredients in their products AND that it doesn’t add to reef barrier breakdown. I only wish the brand wasn’t so pricey, but the benefits are worth it to me.

Terrific sunscreen!
I found out about the Sun screen from a youtuber who does Amazon favorites videos. At first, I thought she was nuts for advertising a $32 sun screen especially for the size it is. I really wanted an everyday sun screen that wasn't thick and goopy. I don't mind of I'm going to the beach or pool but a lot of them are a little much for every day use. Im trying to be better at protecting my face.. When I came across this I decided to splurge and try it. I hate to admit it but I'm so glad I did! It has a slight scent but nothing over powering at all. Its truly a weightless sunscreen that is perfect! I put it on before work and it doesn't make me look greasy or anything. You could probably use it under make up of you really wanted to, I just haven't tried it yet. My only complaint is the price but I haven't tried anything as good ad this! I've seen Ulta have sales on it every once in a while.

Soothing, refreshing, and effective for most uses
I found this sunscreen back when it was still reasonable priced ($10 for a bottle this size) and am now completely 100% addicted as the price continues to rise. Sigh. I don't use this anywhere but my face and neck. Putting this on my face makes me go "ahhhhh". I break out easily, burn easily, and haaaate the feeling of sunscreen. Previously, I used Neutrogena 45 or 55+ ultra-sheer dry touch, and I still use that sometimes when I expect more intense exposure, but the Coola cucumber just feels so much better. I don't actually know if I would burn in cases where I still use my other 45+ sunscreen since I haven't taken the chance. I use Coola for 30-45 minute pool sessions, and hikes between 30-90 minutes. I haven't trusted it for things like skiing, 3 hour hikes, or boating where you get intense sun and a lot of moisture exposure. Buy if you want a lightweight, refreshing face sunscreen for walks in the sun, lounging poolside, or mild-moderate hikes.
