Spray sunscreens—you know ‘em, you probably love ‘em. Around since the 1990s, they remain a tried-and-true sun protection staple, largely lauded for their ease of use and mess-free application. And that’s all very legit. “Spray sunscreens are quick and easy, great for on-the-go, and are also particularly useful for covering hard-to-reach areas, like the back and shoulders,” explains Marisa Gashick, MD, a board-certified dermatologist in New York.
The only issue? While application is easy, it also requires a little bit more dedicated time and attention than you might think; the spray-and-go mentality doesn’t really apply here. “Spray sunscreen is like the elliptical machine at the gym. You have to put effort into it to get a meaningful result,” says Joshua Zeichner, MD, a board-certified dermatologist in New York City. It can become problematic, because, when people aren’t using these formulas correctly, they’re not getting the labeled level of protection—but may have a false sense that they are, he adds. So, how do you ensure that you are in fact applying your sunscreen the right way? Here’s what the derms we talked to had to say.
Hold the can close.
Like, super close. The can should be about an inch away from your skin as you spray, in order to ensure that it doesn’t all just blow away in the wind, says Dr. Zeichner. In related news, Dr. Garshick says it’s also important to apply in an area that isn’t windy. I.e. spraying yourself once you’re on the beach may not be the best idea.
Use more than you think.
A quick misting isn’t going to cut the SPF mustard. Whereas sunscreen creams and lotions come with helpful visual cues when it comes to how much to use (for example, a nickel-size amount for your face and neck), it’s harder to quantify an amount with a spray. Dr. Zeichner’s advice: “Spray until your skin is glistening.”
Rub it in.
Yes, you still have to rub in a spray. Once your skin is glistening, make sure to rub all of that spray in, in order to make sure that you’re getting even coverage and to reduce the risk of missed spots, Dr. Garshick says. And, remember, any sunscreen—sprays included—need to be reapplied every two hours.
Don’t spray it directly on your face.
If you’re using a spray formula on your face, “It’s best to spray the sunscreen into the hands and then apply it to the face,” says Dr. Garshick. This minimizes the likelihood of inhalation, which can be harmful, and/or it getting into your eyes, which can be painful.
TL; DR: The best sunscreen is one you’re going to use. But if that happens to be a spray sunscreen, just make sure to follow the above advice so that it can actually do its protective duties.
