Trader Joe’s Nourish Spray Sunscreen SPF 50 works using BOV pressure technology. Originally created to power turbo- charged engines, it’s now used to power the spray pump on our sunscreen. Think of it as turbo-charged sun- screen. How does it work? It’s basically a valve that uses air pressure to force the sunscreen out of the can, so you get a smooth, continuous stream of sunscreen every time you press the button atop the can. It’s pretty cool. Especially when it’s hot. Nourish Spray Sunscreen SPF 50 provides UVA & UVB protection, contains aloe, vitamin E, and coconut oil. It’s also water resistant. The spray-top twists to lock, making this convenient to toss into a purse, backpack or beach bag, without fear of accidental sprays—just remember to twist it to the “locked” position!
