Excellent quality
Size: 6 Fl Oz (Pack of 2)
I love the Coola brand, and this product does not disappoint. The scent is tropical and not fake-smelling, and I love that the coverage is a wide, fine mist. Because of the way it sprays, I don't have to spend extra time rubbing the product into my skin. I do wish it was cheaper, but it helps protect my skin from burning and it doesn't irritate my skin. Highly recommend!

Smells great and doesn’t mess up makeup
Size: 6 Fl Oz (Pack of 2)
Love this sunscreen. Smells great and doesn’t smear makeup! It is pricey but worth it for me since I am very sun sensitive and need to apply multiple times daily.

My honest review
Size: 6 Fl Oz (Pack of 1)
Having used the COOLA Organic Sunscreen SPF 70 Sunblock Spray, I wanted to share my thoughts on this product. Overall, I found it to be a good sunscreen option, although there were a couple of aspects that prevented me from giving it a full five stars.
On the positive side, the organic formula is a definite plus for those who are conscious of what they put on their skin. The SPF 70 protection worked well, shielding me from sunburn even during extended outdoor activities.
The spray application is convenient and mess-free, making it a great choice for on-the-go use. I also appreciate the eco-friendly approach of COOLA products, which aligns with my values.
However, there were a couple of downsides I encountered. Firstly, the scent of the sunscreen is quite strong upon application. Although it does dissipate relatively quickly, it might be a concern for those sensitive to fragrances. Secondly, I noticed that the spray nozzle occasionally became clogged, leading to uneven coverage at times.
While these issues didn't majorly impact my experience, they did play a role in my overall rating. If COOLA can address the scent intensity and nozzle clogging, it would significantly improve the product.
In summary, the COOLA Organic Sunscreen SPF 70 Sunblock Spray offers effective sun protection with organic ingredients and a convenient spray format. However, the strong scent and occasional nozzle issues led me to rate it four stars. With a bit of refinement, this could easily become a top-tier sunscreen choice.
