Amazing stuff!!
Love love love this stuff! You do have to spread it out well to not go right through it but it doesn’t take more than a thin layer to protect you all day!!

amazing product, a little too pricey
it worked amazing while we were trying to swim in the ocean and snorkel in the ocean. The only downfall I have of this is the price is so much for such a little amount.

My go to brand
My go to brand. Other brands I have to reapply constantly and still have sunburn. I love this brand and the stick is even better for applying sunscreen. Very reliable without any mess!

Not fur Surfing or other Water Sports
I got this in a swag bag from a surfing contest. The stick is very dry...that's the only way I can explain how it feels. It certainly doesn't glide on like other face sticks. After one wave and ducking my face in the water, the product smeared off and ran into my eyes. My vision got blurry from that, and it was really hard to see the waves coming in. I won't be using this product ever again. I also looked at the EWG website, and this product was given a 6. For those new to EWG, that's not a good rating. You want like a 1 or 2.
