Spray Sunscreens Are Effective When Used Correctly

Spray sunscreen has become a go-to summer staple especially for beach days, hikes, or busy mornings when you need quick, no-mess coverage. But can you trust sprays to protect your skin as well as lotions? The short answer: yes, if used properly.

Dermatologists agree that spray sunscreens are just as effective as lotion formulas, but there are important caveats when it comes to application and safety.

How Spray Sunscreens Work

Spray sunscreens use a misting delivery system to disperse a fine layer of sunblock across your skin. Like lotions, they contain either chemical filters (like avobenzone or oxybenzone) or mineral filters (like zinc oxide or titanium dioxide) to protect against harmful UV rays.

The difference is in the delivery not the protection itself.

"Spray sunscreens work just as well as creams or lotions as long as you use them correctly," says Steve Daveluy, MD, a board-certified dermatologist.

Application Tips to Maximize Protection

The main issue with spray sunscreens isn't the formula it's how people use them. Missed spots and thin, uneven coverage are common with sprays, especially in windy conditions.

To apply spray sunscreen effectively:

• Hold the nozzle close to your skin (around 4 to 6 inches away).

• Spray until your skin glistens, ensuring even coverage.

• Rub it in yes, even with spray. There's no such thing as a true "no-rub" formula.

• Avoid spraying your face directly. Instead, spray onto your hands and then apply it to your face.

• Don’t spray in windy conditions you may not get enough coverage.

• Reapply every two hours, or after swimming or sweating.

Be Cautious of Aerosol Propellants

Recent recalls of certain spray sunscreens raised concerns after traces of benzene, a carcinogen, were detected. Experts believe the benzene contamination came from aerosol propellants not the sunscreen ingredients themselves.

To reduce risk:

• Look for non-aerosol sprays.

• Avoid using sprays near open flames or heat sources, since most contain alcohol and can be flammable.

According to the FDA, exposure levels in recalled sunscreens were generally much lower than those from smoking or gasoline, but it's still smart to choose clean, well-tested brands.

When Spray Sunscreen Makes Sense

Spray sunscreen is especially useful when:

• You’re on the go and need quick application.

• You’re exercising or sweating, since sprays go on easily over damp skin.

• You need to reach hard-to-access areas, like your back.

• You have kids who hate lotion (just make sure to supervise application carefully).

Should You Choose a Mineral Spray?

If you have sensitive skin, opt for a mineral spray sunscreen. These products use physical UV blockers like zinc oxide or titanium dioxide, and are less likely to cause irritation or allergic reactions.

“Mineral sunscreen is safer than safe,” says Dr. Daveluy. “These are the same ingredients we use in diaper rash creams for babies.”

Just keep in mind: mineral sprays still need to be rubbed in for best results.

The Bottom Line

The best sunscreen is the one you’ll use consistently. If sprays fit your lifestyle, there’s no need to shy away as long as you apply them thoroughly and safely. Be mindful of product ingredients, especially propellants, and take time to ensure full coverage.
