I love this sunscreen mist for the face. I have tried many facial sunscreens to protect against the Arizona sun and this is by far the best. So many sunscreens have a heavy feel, make my face sweat more, and end up clogging my pores. This sunscreen has a light, pleasant smell and is a lightweight spray. You spray it into your hand and smooth it on your face and neck. It feels hydrating without any heavy or greasy feel, and you can use foundation over it if you wish. It has done a great job protecting my skin, and just as important for me, it does not clog my pores and cause complexion issues. I have pretty sensitive facial skin and this has not caused any irritation at all. It is definitely worth trying and then buying again when you love it.

Not great

Size: 2.1 Fl Oz (Pack of 1)

I wish I could give 3 1/2 starts but I have to give it 3 stars for two reasons. 1 is it is not a fine mist, it will leave your face looking crazy after you spray it. You end up having to pay it into your skin because there’s white splotches all over your face. So if you were to apply this with no mirror it would be a problem. Also I feel like it semi defeats the point of using a face spray if you have to use your hands to finish applying it. 2 is that for me it makes my skin feel hot and kinda burn around my mouth area. I think there might be too much fragrance or something. It does go away after awhile but it is not pleasant and I can’t imagine it is good for me.

Great for summer pool time

Size: 2.1 Fl Oz (Pack of 1)

Gave it 5 stars because it really does its job. I used this sunscreen on my face during the summer when I was going to the pool a lot. It goes on white at first, but once you rub it in well the white cast pretty much disappears. Doesn’t make my face super greasy and protected my skin really well, no burns, no weird tan lines, nothing, as long as I reapplied it like the instructions say. The smell is light and not annoying. The bottle is small and easy to keep in a bag. Overall, a good product that actually works.
