Great feel but a bit strong of a smell
I absolutely love the feel of this sunscreen, since it feels really smooth and light weight. There is no white stain from sweating and feels really moisturizing. The only thing I dislike is the strong fragrance. I personally don't like fragrance in my beauty products, but I wanted to try this sunscreen due to the high reviews. I think this is a great sunscreen to buy, but for me personally, I would not buy again simply due to the smell though it does smell good. I will try out the fragrance free version.

Perfect for Travel and Gentle on My Son's Skin!
Style: Spray (2 Oz)
First off, the size is perfect for going through TSA. We had no issues bringing it in our carry-on, which made traveling so much easier. The convenience of having a high-quality sunscreen that’s travel-friendly is a huge plus.
What really impressed me is how gentle it is on my son's skin. He has sensitive skin that tends to dry out with other sunscreens, but this one kept his skin moisturized and protected all day. No dryness or irritation at all!
And the smell is amazing! It has a pleasant, natural scent that isn’t overpowering. Applying it was a breeze, and the spray format made it quick and easy to cover all areas evenly.
If you're looking for an effective, travel-friendly sunscreen that’s gentle on sensitive skin and smells great, I highly recommend the OOLA Organic Sunscreen SPF 30 Sunblock Spray. It's become a must-have in our sun care routine!
