Shopping for a red light mask can feel tricky. On one hand, you want a device that delivers on its promises and offers results you can actually see. On the other, you might not be ready to commit to a high-priced model. With so many options out there, it’s easy to get duped—and the last thing you want is to invest in a device with spotty coverage or poor performance.
“The data is pretty satisfying for many of these devices, but the degree to which they help is often overstated,” says West Palm Beach dermatologist Jacob Beer, MD. Instead of relying on testimonials alone, it helps to turn to the professionals. Ahead, two dermatologists share what to know before buying a red light mask, including the factors that matter most.

In-Office vs. At-Home Treatments
LED (light-emitting diode) therapy uses different wavelengths of light to target various skin concerns. Each wavelength corresponds to a specific color and depth of penetration. Red light therapy is the most common of the group and a powerful tool for addressing signs of aging. Because it works at a 600–700 nm wavelength, it can reach beneath the surface to stimulate collagen, improve elasticity and reduce fine lines and wrinkles. It can also boost circulation and reduce inflammation—benefits that apply to virtually any skin type.
Thanks to these perks, red light therapy has become popular both in-office and at home. But there’s a big difference between the two. In-office treatments, whether delivered through a mask or panel, are more powerful and can produce more dramatic results in fewer sessions. New York dermatologist Jody A. Levine, MD adds that in-office use allows for customization, making these treatments generally more effective. “At-home devices, such as red light masks, have less power and are instead a convenient way to maintain results in between in-office treatments,” she says.
Offsetting the difference in potency comes down to consistency. “Since at-home devices are much lower intensity, they must be used frequently to see results,” says Dr. Levine. Dr. Jacob Beer agrees, noting that diligence is key if you want to reap the benefits. While at-home devices won’t match the strength of an in-office session, he says sticking to a routine can lead to noticeable improvements. He recommends using facial devices two to three times per week for at least 15–30 minutes.
Factors to Consider When Shopping
Red light masks are more popular than ever, according to Spate, and consumer interest continues to climb. But not all devices on the market are created equal. Quality varies widely, and several factors determine how effective a device will be. First is the device’s intensity and wavelength specifications. “There are multiple devices on the market that fall outside of the wavelength of efficacy,” says Dr. Beer. “For skin rejuvenation, a wavelength around 633-830 nanometers is required to promote collagen stimulation.”
Energy output is just as important. According to Dr. Levine, irradiance, or the measure of light energy, must be between the clinically proven range, 30-100 mW/cm2, to be effective. Beyond specs, it’s also important to look at clinical trials and FDA clearance. As Dr. Beer explains, proper testing is essential for understanding how a device will perform. “If it’s a newer device that’s outside the wavelength range and without any clinical trials, it will likely not provide the results you’re looking for,” he says.
Is Price Important?
You may be surprised—and happy—to learn that price isn’t the most important factor when shopping for a red light device. While some models cost over $1,000, a higher price tag doesn’t automatically mean better quality. “You don’t always have to go boutique to find a good device,” says Dr. Beer. “In fact, there are some sold at Costco and Sam’s Club that offer good results.”
Instead of comparing price tags side by side, Dr. Levine says you’ll get more insight by focusing on the other factors, especially energy output and wavelength specifications. That said, she notes that a red light tool that does meet clinically proven standards is generally going to be an investment.
