Difficult to rub in; sweat and water resistant; difficult to wash off
Style: SPF 50, Size: 5 Ounce (Pack of 3)
I've used this spray sunscreen off and on for the past two years and have now decided to only use it after a long and sweaty work out at the gym when I drive home. It is much easier to apply onto the skin on sweaty/wet/moist skin than on dry skin. It is difficult to apply and rub in on dry skin. One should carefully apply and use a finger to do so to minimize stretching the skin. The positive about this sunscreen is that it is sweat resistant and will not seep or run into your eyes. It is also water resistant; therefore, it is a good sunscreen to use if you are going swimming. However, this makes it difficult to wash off, even in the shower using a face wash or scrub. I would not recommend this sunscreen for daily use. If you are wearing sunscreen for the purposes of avoiding incidental sun exposure, such as driving to and from places, locally, for fewer than 20-30 minutes, or if you are going for brief walks outside, use a different sunscreen that is friendlier on the skin. I WOULD recommend this sunscreen to anyone that plans on spending prolonged periods of time out in the sun, including being exposed to direct sunlight. If you are planning a day out at the beach, or going out swimming, exercising outdoors for over 30 minutes, taking a long road trip, or planning to do any activity where you will be in direct sunlight, this is a good sunscreen to use. It will leave a white cast, however, I have confidence that it will provide the adequate protection against UVA-1, UVA-2 and UVB radiation to protect your skin.

Good sunscreen
Style: SPF 50, Size: 5 Ounce (Pack of 1)
Great alternative to chemical sunscreen, spray is a little patchy and leaves a heavy white residue but that is to be expected. Works well and prevents sunburn so it's a win.

Great mineral spray sunscreen
Style: SPF 50, Size: 5 Ounce (Pack of 1)
Purchased multiple times over the years. Great mineral spray sunscreen for sensitive skin. Does leave a white cast but that’s not a huge deal for us. Nice option for kids with sensory issues that hate goopy sunscreen.

Sun protection without the chemicals!
Style: SPF 50, Size: 5 Ounce (Pack of 3), Style: SPF 50, Size: 5 Ounce (Pack of 3)
I searched for a long time to find safe sunscreen. Prior to having kids, the ingredients in sunscreen (and many other things) were not a concern. Now, I do my best to make sure that anything going on my kids’ skin is as safe as possible. After hours and hours of searching, I finally found this product. It was more than I wanted to spend, but now that I’ve used it I won’t go back! My sons skin is as light as a sheet of paper and he doesn’t like to wear a shirt, so having great sunscreen is important. I use it for both kids as well as my husband and myself. I do not agree with the reviews stating that this sunscreen is hard to rub in; I find it quite easy! Just bought another pack for this summer!
