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.

Too little product for the price

I was surprised at how little product you get for the price. After only two weeks, the bar already broke in half, and there's not much left. Additionally, it leaves white streaks, so you'll need to rub it in after applying. I still like the fact that it's got clean organic ingredients. I won't by the bar again, but I will try the spray

Bad smell

Item Package Quantity: 1

Smells really weird. Not at all like a normal spf or any cosmetics product normally does. It’s like a plastic smell. The glitter is ok but I’m not sure this mist actually blocks any UV/ sun.
