Background
Cytokeratins are proteins of cytoskeletal intermediate filaments, and their main function is to enable cells to withstand mechanical stress. In humans, 20 different cytokeratin isotypes have been identified. Cytokeratins 8, 18, 19, and 20 have been associated with bladder. Cytokeratin 18 (KRT18, also called K18), found in epithelial cells, is released from hepatocytes upon death.

It works well, but it’s expensive and greasy
Size: 6 Fl Oz (Pack of 1)
As far as sun protection goes, this has worked perfectly for my family. Spray it on, blend it in, good to go. No sunburn. There are a few annoying things about it though. The price is incredibly high, imo. It is unscented, which is rare for sunscreen, but it smells like alcohol when wet. Also, this stuff is oily. It makes everything it touches greasy looking (hair, clothes, hands…) I like this overall for an alternative to thick mineral sunscreens. It’s pretty convenient.

Great for sensitive skin
Size: 2 Fl Oz (Pack of 1)
I have extremely sensitive skin and recently found out my skin hates the sun due to my autoimmune issues. This sunscreen doesn't break my skin out, keeps me from getting sunburnt and doesn't have a bunch of fragrance. This travel size has been perfect for throwing in my bag for a day at the baseball park or beach. This is a non greasy and no whitecast spray that has a high spf too. I highly recommend it.

Apply BEFORE leaving the house!
Size: 6 Fl Oz (Pack of 1)
I have fair (freckle don’t tan, burn easily then peel and back to white) and sensitive skin. So does my son. I live on the coast, in a southern state and vacation in the Caribbean often. After too many years of getting burned, I finally found Coola a couple years ago. It has revolutionized my time in the sun.
Here’s the thing tho. If you don’t apply it properly, it’s not gonna work. If you’re looking for something to put on AT the pool or beach, go for something else (with zinc oxide preferably). If you’re willing to take 5 mins before you go to do it, you’ll be very happy. Kids especially are hard enough to get covered before they see water anyway!
Here’s some tips:
Spray everyone OUTSIDE (even the unscented can overwhelm inside, and you really don’t need to be breathing in ANY sunscreen)
DO NOT USE ON FACE. It will burn your eyes when you sweat/swim. Choose a cream or face stick.
Spray until skin is wet. You’re not looking for a light misting, you’re going for full coverage. The can can sound like it’s spraying, but if you don’t see the product on the skin, you’re gonna get burned.
Give it 5 mins to dry before putting on shirts/cover ups.
Reapply between 2 & 3 hours of water exposure. (We usually dry off, respray, then have a snack or lunch) Give it 15 - 20 mins to soak in before you hit the water again.
I’ve found a 6oz can will usually take care of two adults and a child for the day (initial and resprays). It’s a tad expensive, so we use Coola on days we plan to be out for more than a couple hours, or every day in the Caribbean, since the sun is SO intense.
The 2oz is ‘touch up’ sized. It may take care of a child’s initial spray, but I’ve found it more suited for adding additional spray to areas that feel a bit crispy, rather than using it on a single application.

Toxic ingredients
Size: 2 Fl Oz (Pack of 1)
There are endocrine disruptors in here that are harmful to your health. I nearly got to the point of being disabled from endocrine issues. Has ingredients that ruin fertility, raise risk of cancer, and ruin your endocrine system. I hope these brands can take these ingredients out and begin to care about consumers health.
