No white residue
Size: 3.4 Fl Oz (Pack of 1)
I put this sunscreen on immediately after it was delivered. It smells so good & goes on smoothly without any white residue. It seems to protect the skin, but then again I put some on every hour on the hour and didn't have any issues. I will be reordering. I wish this was on subscribe and save, but will continue to purchase.

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!
