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.

Tried + tested on Caribbean vacation
Size: 6 Fl Oz (Pack of 1)
First let me start by saying I have an inflammatory condition so I needed a sunscreen that didn’t contribute to making my symptoms worse like many of the other sunscreens with harsh chemicals. This sunscreen is phenomenal! We just got back from a week in the Caribbean sun in Antigua/Barbuda, and I did not burn once! But there are some key things you must know before buying so that you can apply it properly and get the best protection. First, you must shake the can for about 20 seconds before each use. This way it mixes the sunscreen and applies it correctly. If you spray it and it comes out clear you have not shaken it up enough. It should spray solid white. Second, rub it in quickly after you spray it because it dries fast. Note that this does leave a white cast, but it’s not as bad as everyone says. I have light olive skin (half Hispanic, half white) and I tan easily but I also burn easily. When I applied it, it went on white but I just took the time and rub it in really well. The white cast will fade a little once it dries but it will also sit on top of the skin which is helpful to know when you need to re-apply. I applied in the morning about 20 min before getting in the sun. *Apply before putting on your swim suit! If it gets on your swimwear, it will leave white marks*. The sunscreen stayed on through pool and ocean use without rubbing off. I only needed to reapply on the tops of my shoulders once in the afternoon. Also, this is not to say that you won’t burn. While I was in the intense sun, I also spent time in the shade throughout the day just to make sure I was giving my skin breaks from the heat. But for being in the sun like I was, I am VERY impressed with this sunscreen. And for it only being spf 30, it protected me better than expected in the harsh Caribbean sun. I usually come home from vacations with a little burn but absolutely none this time! Just be sure to take time to apply it correctly and you should be good! I’d rather have a slight, minimal white cast than be burnt and miserable. It’s worth it! I’ll be using this stuff from now on.

I am super white and have great skin which is super surprising ...
I just started using this product and I wanted to write because I thought some of the reviews were mixed when I read them. I used to use Zinka's spray but they changed their formula and now it is a greasy mess, that never dries do not buy that, I wrote the company and they do not care. First and foremost this bottle is heavy so I am not sure if the shaker ball is heavy or what but a 6oz bottle should not be this heavy so that might be a marketing ploy, hope I don't run out and just have a shaker ball. I am super white and have great skin which is super surprising as my childcare was being dumped off at the local pool in TX without sunscreen during the summers, but I attribute that to using a zinc based sunscreen for the past 10-15 years. I use this everyday, rain or shine as I live in TX and it never rains long and winter here has sunshine too. I use it on my face, hands and decolletage. Yes, my face, under my make up or not. Here are the issues, this makes a super white paste that does not fade into the skin if you go too heavy. So you have to rub it in and even then there is a whiteness, and I am already a white gal. I too am longing for a day of clear zinc sunscreen. But none on the market I have found that are not an oily mess that cause breakouts. I like the dry texture of this spray, and if I spray a thin layer I do not need to rub, so that is perfect for me on my face as most make up I put over it has spf protection anyways, so no problem there, and this stuff stays on 12 hours or more. I think the cost is high, I used to pay around $10 a bottle for zinka but it was not as heavy as this so I will see how long this lasts. But so far except for the cost and the having to rub it in I really like this product.
