It is quick to apply and I've never gotten a burn with it. It doesn't leave marks on my clothing.
Size: 6 Ounce (Pack of 2), Style: SPF 50
I've used this product for years. I spray it into my hands to apply so it doesn't go out into the air. I have never gotten a burn with it and it is. so easy to apply. I don't have to worry about white marks in my clothes. It doesn't take long to apply.

Affordable and Effective
Size: 6 Ounce (Pack of 2), Style: SPF 50
It’s really good for the price and super easy to apply. I would recommend having someone help with your back or harder-to-reach areas, because any spots you miss will definitely show if you’re out in the sun for a while. I’ve used this for a couple of years now, and it’s one I keep going back to. If you have more sensitive skin, there may be better options out there, but I personally haven’t had any issues with it so far.

Us it Every Day
Size: 6 Ounce (Pack of 2), Style: SPF 50
This is really a great product and easy to use as a spray. I bike ride every day and my ears/face are exposed to the Florida sun. I use it primarily on my face every day. A moment after a quick spray, the product dries, is not sticky, etc. This will become a recurring purchase.

Good protection from the sun.
Size: 6 Ounce (Pack of 2), Style: SPF 50
Does a good job keeping sunburns away. Spray sunscreen never lasts as long as rub-in sunscreen (ie, the bottles run out quicker) so it seems pricier to cover the whole family, but we keep this on hand for days we'll be outside!

Lightweight and moisturizing
I use almost all of the TruSkin line.
This facial serum is fantastic like all the rest.
I have had no irritation or breakouts with it and have used it in combination with their other facial serums.
The serum is light, and absorbs quickly.
