We basically live in the golden age of sunscreen. Less than 50 years ago we were stuck with just a handful of options (and none were that great), but today you can find a plethora of formulas across different brands ranging from gels, oils, serums, lotions, and creams. Powder sunscreens are another option, but some people wonder whether they really work and, if they do, how to use them. With expert help, we’re shedding some light on this unique SPF category, offering some best-case use examples, and sharing our favorite products.
What Are Powder Sunscreens?
True to their name, powder sunscreens are dry, loose powder formulations that are applied with a cosmetic brush. They’re considered a “physical sunscreen,” meaning they’re made with natural, mineral-based ingredients—including zinc oxide and titanium dioxide—that provide broad-spectrum protection against both UVA and UVB rays.
“Powder sunscreens can be an excellent choice for convenient sunscreen reapplication over makeup,” says Blair Murphy-Rose, MD, board-certified dermatologist and founder of Skincare Junkie.“Some may prefer the feel and application of powder sunscreens, as they are non-greasy and often provide a matte finish.”
She adds that a pure mineral powder sunscreen may also be better for people with skin sensitivities who’ve had a difficult time finding a sunscreen that doesn’t irritate their skin. Along with using them on top of makeup, they can also come in handy for protecting your scalp from the sun.
Do Powder Sunscreens Actually Work?
Powder sunscreens are often considered a less protective form of sunscreen compared to other formula types.
“In theory, powder sunscreens should be as effective compared to other forms of sunscreen with the same SPF so long as they are applied correctly, but an issue with all sunscreens is that many users will not apply them correctly,” Dr. Murphy-Rose says. “Powder sunscreens are more susceptible to this problem because they must be applied generously enough to achieve the labeled SPF, and often are not.” Another factor to consider is that many powder sunscreens don’t hold up as well to water or sweat compared to liquid versions.
Ultimately, Dr. Murphy-Rose says that she wouldn’t personally recommend a powder sunscreen over another type unless it was preferred by someone for some of the reasons mentioned above.
When to Use Powder Sunscreens
If you have skin sensitivities or allergies and can’t tolerate other formulas
Those dealing with oily skin issues and want a mattified effect
When applying SPF over your makeup
Applying SPF to protect your scalp
It’s the only type of sunscreen you like
That said, when you do use powder sunscreens, Dr. Murphy-Rose says they really should only be used in small areas versus the entire body. Also, make sure to to clean the brush weekly like you would other makeup brushes since they can accumulate oil, sweat, dirt, and bacteria.
