How to Actually Use Spray Sunscreen So It Works

A quick spritz leaves you barely protected — here's how to use spray SPF so it actually does its job.

By the numbers

Spray sunscreen should be applied until the skin glistens and then rubbed in for even coverage; it should not be sprayed directly onto the face, and it should never be used near heat or open flame.

The American Academy of Dermatology advises spraying until the skin glistens and then rubbing it in, and the FDA warns against applying flammable spray products near heat or flame and against spraying directly on the face.

Questions we get a lot

How much spray sunscreen should I use?

Enough that the skin glistens, then rub it in to spread it evenly. A quick, light mist usually leaves gaps and far less protection than the SPF on the label implies. Reapply at least every two hours and after swimming or sweating, just like with lotion.

Is it safe to spray sunscreen on my face?

Don't spray it directly on your face. Instead, spray it into your hands and then apply to the face to avoid inhaling the product or getting it in your eyes. Also keep spray sunscreens away from heat, sparks, and open flame, since many are flammable.
