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.

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!

Smells great and works great too!
Style: Spray (2 Oz)
Great sunscreen and smells fantastic. Not sticky or greasy feeling, but the bottle seems a bit small for the price. Took it to the beach for the 4th of July week and it was the first time I didn't come back with my "base burn". So it really works well. Great size for carry-on travel, but again a bit pricey for the amount you get.

Amazing smell amazing feel
Style: Spray (6 Oz)
Product arrived without damage! My absolute favorite sunscreen! If it’s ever on sale, I highly recommend trying as it’s not the most affordable. Never makes me feel greasy and is so lightweight! I never have breakouts with this either. Smell just adds to my obsession more too
