Why I Don’t Recommend Spray Sunscreen

Skincare
Written By Alison Dempsey

This week, I issued a warning to my group chat: if you bring spray sunscreen to the Hamptons, we are no longer friends. Was I being dramatic? Maybe a little. But only because I love my friends and want to protect their gorgeous faces. I don’t want to see them in my office a few years from now for anything but beauty maintenance.

As a board-certified dermatologist, I’ve seen the effects of “lazy SPF” and I need to set the record straight. Here’s why I don’t recommend spray sunscreen… and what you should use instead.

You’re Not Using Enough

The American Academy of Dermatology (AAD) recommends using one ounce (a shot glass worth) of sunscreen to cover all exposed skin not covered by clothing. That’s about a nickel-sized amount for the face and neck, and teaspoons for limbs. With sprays, most people apply only 20–50% of the needed amount. That’s basically skipping SPF in some spots. It’s not the product, it’s the math.

If You Can’t See It, You Can’t Trust It

Sprays go on invisibly and often unevenly, especially in the wind. Without a visible layer to rub in, you’re just hoping for full coverage. Hope is not a skincare strategy.

You’re Inhaling It (and So Is Everyone Around You)

Spray sunscreen is not meant to be inhaled. Whether it’s oxybenzone or mineral particles, your lungs weren’t invited to the SPF party. This is especially concerning for children and anyone with asthma.

It’s Wasteful, Flammable, and Just… Meh

  • You lose product to the air.

  • You risk flammability (yes, there are actual warning labels).

  • Many formulas aren’t reef-safe.

So What Should You Use Instead?

Lotion or cream sunscreens. They offer better coverage, easier measurement, and real protection. I personally recommend:

If You’re Naughty and Still Want to Use Spray Sunscreen (I’m Looking at You, Dad)

Okay, fine. If you must use spray sunscreen, whether it’s because you forgot your lotion, you’re reapplying over makeup, or you’re just that stubborn… here’s how to do it right.

1. Spray until your skin looks wet.
This isn’t a gentle mist situation. Keep spraying each area until there’s visible saturation — like a fresh glazed donut, not a dry dusting.

2. Rub. It. In.
Yes, even if it says “no rub.” You need to ensure even coverage across every inch of exposed skin. Otherwise, you’re leaving patchy gaps that UV rays will happily exploit.

3. Don’t spray in the wind.
If half your sunscreen is going into the atmosphere, you’re wasting product and getting burned. Spray in a sheltered area (or even indoors before heading out), and never on or near your face — use a lotion or stick instead.

4. Don’t breathe it in.
Hold your breath while applying, move away before inhaling, and avoid using sprays on kids or near the face. Your lungs did not consent to chemical filters or propellants.

5. Reapply every 2 hours — more often if swimming or sweating.
No exceptions. Spray is even more likely to rub or sweat off than creams.
