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.

My favorite sunscreen
Size: 6 Fl Oz (Pack of 1)
I love this sunscreen and have been carrying a can in my bag all this summer. To address a couple of common complaints:
“It’s not sheer at all”: “Sheer” does not mean the same thing as “clear,” people. This spray is white and absolutely does rub in to be sheer as advertised. It leaves a slight (“sheer”) white tinge after rubbing in, but it’s not super noticeable on my pale skin. It might be more problematic on darker skin tones. (Also, it should be noted that there is literally no such thing as clear mineral sunscreen- you will have to choose between a product like this and a clear one containing endocrine disruptors. I’d rather look a little pasty, personally.)
“My whole family used this and got burned”: You need to shake the can before spraying, as per the instructions. These sprays are made of zinc (the active, protective ingredient) in a liquid suspension. If you spray without shaking the can first, you risk getting all liquid and no zinc particles, and then yes, you will burn. I’m pretty sensitive and this sunscreen has not failed me yet.
“It’s hard to get off”: This is true. It is hard to get off. But why would you want a sunscreen to come off easily?? This stuff is water resistant to an impressive degree. In the evening if it takes a vigorous scrubbing to get it off, I consider the exfoliation a bonus.
Also, my nozzles have worked just fine and the cans last me quite a good amount of time.

It really is water resistant
Size: 6 Fl Oz (Pack of 1)
This stuff is great. Normally when buying a green sunscreen, I have to sacrifice the aerosol feature and default to a lotion. This has a very neutral scent and sprays easily and evenly. It is zinc-based, so it will leave a white haze on your skin. I did need to rub it in after spraying, which helped minimize the white hue. It does love bathing suits, so be prepared to also rub the zinc powder into your bathing suit, otherwise it will be spray painted white. I used this while tubing and did not get burned--just nice and toasty-tan. The biggest downside is that it has a very slight stickiness/tackiness to it. I showered twice before I finally felt like it was all off my skin. But at least it didn't come off in the river!

Leaves skin WHITE and chalky!
Size: 6 Fl Oz (Pack of 1)
This sunscreen is the worst. it leaves your skin feeling chalky, and totally white. it is difficult to get it off. I accidentally bought it twice two years apart thinking it was the one I liked, but nope. floated the river and even trying to rub it off in the water wouldn't remove the white cast on my skin all day. If you don't mind chalky skin and looking white, then go for it.
