What matters more than spray versus lotion?
For either format, choose broad spectrum protection, SPF 30 or higher and water resistance. Broad spectrum means protection against both UVA and UVB, the two forms of ultraviolet radiation that damage skin. SPF mainly describes protection against UVB, the rays responsible for sunburn. The useful comparison is the protection on the label and the coverage on your skin, not which bottle has the more dramatic delivery system.23
| Practical difference | Spray sunscreen | Lotion sunscreen |
|---|---|---|
| Application | Spray generously, then rub in for even coverage. | Spread enough product over all exposed skin. |
| Knowing you have enough | Harder to judge; spray until skin glistens. | Use the recommended amount rather than a thin smear. |
| Face application | Spray onto your hands first, then apply. | Apply directly with your hands, avoiding eyes and mouth. |
| Wind | Avoid spraying on windy days. | Does not require spraying into the air. |
| Reapplication | About every two hours outdoors and after swimming or sweating. | The same reapplication rules apply. |
Choose lotion if you would rather avoid judging spray coverage or need sunscreen for windy conditions. Spray can be a useful choice for children's bodies because it is often easier to apply, provided you use enough and rub it in. For sensitive skin, consider a mineral sunscreen containing zinc oxide or titanium dioxide; choosing a spray rather than a lotion is a separate decision from choosing those ingredients.12
How do you apply spray sunscreen correctly?
- 1Read the bottle's directions and apply to dry skin before going outdoors.
- 2Hold the nozzle close to your skin and spray generously until the skin glistens.
- 3Rub the sunscreen in thoroughly to spread an even layer and cover missed spots. Spray sunscreen still needs rubbing in, so the nozzle has not retired your hands.
- 4Cover every exposed area, including your neck, ears, hands and tops of your feet.
- 5Reapply about every two hours outdoors, and after swimming or sweating, following the bottle's directions.
Avoid inhaling spray sunscreen and do not use it on windy days. Never spray near heat or an open flame, or while smoking. Aerosol sunscreen can be flammable; rub it in thoroughly and let it dry before approaching an open flame.2
Can you spray sunscreen directly on your face?
No. Spray sunscreen onto your hands first, then apply it to your face, avoiding your eyes and mouth. Do not spray around or near your face or mouth, even if you intend to rub it in afterwards. The same application precautions matter when applying spray sunscreen to a child.2
How much spray sunscreen should I use?
Most adults need at least about one ounce, roughly a shot glass, to cover skin not covered by clothing. Larger bodies can need more. For the face, use at least one teaspoon. With spray, use glistening skin as the application cue before rubbing it in. A typical six ounce spray bottle contains about six applications, not an entire summer's supply.12
Does spray sunscreen last as long?
Neither format removes the need to reapply. Apply sunscreen 15 minutes before sun exposure. Water resistant products state whether they remain effective for 40 or 80 minutes while swimming or sweating; follow the label's reapplication directions. No sunscreen is waterproof. Keep either bottle out of excessive heat and direct sun, and do not use expired sunscreen. Use shade and protective clothing alongside sunscreen rather than relying on the bottle alone.34
