Product leaks into the cap
Size: 3.4 Fl Oz (Pack of 1), Size: 3.4 Fl Oz (Pack of 1)
The packaging appears to be defective and potentially tampered with. Specifically, the nozzle is a different color from the rest of the tube—one that is not consistent with the brand’s standard packaging (I am familiar with this brand and have purchased it before). Additionally, the cap does not close properly, causing the product to leak into the lid and resulting in unnecessary waste.
This raises serious concerns about the product’s authenticity, quality control, and whether it may have been previously opened or altered.

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.
