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.

Works & Smells Great
Size: 6 Fl Oz (Pack of 1)
This product smells so nice and isn't sticky or tacky on the skin. I feel like it absorbed quite well. We used this in Vegas recently and I had a few soft red spots that went away a couple days later. Yes, we re-applied, but it is VERY bright in Vegas at the pool. This will probably become my go-to spray sunscreen. As my mobility can be limited, spray sunscreens have really helped me make sure I get all areas that are exposed to the sun.

Love this!
Size: 6 Fl Oz (Pack of 2)
I normally hate all sunscreen. I dont like lotion or anything on my skin cause I feel trapped. This is light and covers well. I am a softball coach so I am used to being out in the summer time with fair skin. I used as recommended and did not get burnt once. and the Peach Blossom smells great without being overpowering.
