The best red light therapy devices for 2025: Treat yourself to some RLT

Red light therapy (RLT) isn't just another wellness fad. Endorsed by scientific evidence and a growing body of research (although more research is still needed), the best red light therapy devices show promising results when it comes to reducing wrinkles, boosting hair growth, even easing chronic pain caused by inflammation. Some research even indicates that red light therapy can be a useful adjunct to traditional therapies for neurological disorders, cognitive function and obesity.

While other light therapies exist, red light therapy — technically called photobiomodulation — uses longer wavelengths, including near-infrared and infrared light, that penetrate deeper into your body than other light colors, according to Dr. Frank Lipman, chief medical officer at the Well in New York City

The key to enjoying the potential benefits of these devices is to identify products that use clinically-backed wavelengths of light, typically ranging from 600 to 900 nanometers (nm). At these wavelengths, red light therapy has the ability to stimulate the mitochondria — parts of your cells that produce energy. "This supports the body's natural healing processes to reduce inflammation and redness, increase collagen production, diminish the appearance of wrinkles and fine lines and promote healing," Lipman says.

The results can be impressive: One study found that after just eight treatments spread over a month, more than 90 percent of users noticed smoother skin, less redness and lighter dark spots. While that's exciting, keep in mind that the American Academy of Dermatology Association (AADA) suggests thinking of red light therapy as one piece of your skincare puzzle — not the whole solution. And heads up if you have a darker skin tone: You'll want to chat with your dermatologist before jumping in, since research shows you might be more likely to develop stubborn dark spots from the treatment.

Ready to give it a try? The good news is you no longer have to visit a high-end spa or a doctor's office to reap the RLT rewards — or pay a premium to do so. Thanks to a growing market of at-home devices, including masks and full-body panels, it's easier than ever to bring the benefits home.

To help you choose the best at home red light therapy device for your needs, we turned to three skin and health experts for their insider advice and we researched over two dozen options. After rigorously testing the top 10 for ease of use, features, comfort, design and results, we found top performers in every category — from portable units to professional-grade panels, including targeted tools for face and pain relief.

Types of red light therapy devices

Today's red light therapy devices use gentle LED (light-emitting diode) technology to deliver specific wavelengths of red and near-infrared light that stimulate cellular activity and promote healing — all without generating excess heat. Whether you're targeting wrinkles, soothing sore muscles or boosting overall wellness, there's a device designed for your needs. From portable handheld tools to comfortable masks to powerful full panels, here's a guide to finding your perfect match:

• Handheld devices: These compact red light therapy tools are ideal for spot treatments, letting you target specific areas like your face, joints or scalp. Their focused design makes them especially popular for addressing fine lines, acne or localized pain. While they're travel-friendly and often more budget-friendly than larger devices, you'll need to move them around manually — which can take extra time if you're treating larger areas.

• Red light masks: Designed specifically for the face, these wearable red light devices often combine red and near-infrared LEDs to help increase collagen production, reduce wrinkles and calm inflammation. Some are rigid and made of harder plastic, while others are made from flexible — and more comfortable — silicone for longer wear.

• Panels and full-body devices: Red light panels — flat, grid-style devices covered in LEDs — let you treat large areas of your body at once. Simply stand or sit in front of these rectangular or square units, which come in various sizes. "Full-body exposure to red and near-infrared light can have metabolic and immune benefits beyond skin health," says Lipman, making these devices especially valuable for athletic recovery, muscle and joint pain or systemic inflammation. While panels are most common, you'll also find full-body red light therapy bed devices that resemble tanning beds or sleeping bags. Just note that these larger setups command both a bigger budget and more space than handheld tools or masks.

• Combination devices: Some red light therapy tools incorporate multiple technologies or wavelengths. For example, you might find a red light device for the face that offers red light, near-infrared light and even blue light (commonly used for acne). These are great for users who want a multitargeted approach, like treating signs of aging, breakouts and inflammation all at once.

Factors to consider when purchasing a red light therapy device

Scrolling through endless Instagram ads of glowing faces and too-good-to-be-true before-and-afters? While those viral LED masks might be tempting, choosing the best red light therapy device isn't about chasing the latest sensation. Experts say that, instead, your perfect match depends on your wellness goals, how consistently you'll actually use it and the practical realities of your space and schedule. Here's what matters most:

• Wavelength: Different wavelengths penetrate the skin at different depths, says Timothy Demchak, a professor of applied medicine at Indiana State University. For optimal results, look for devices that offer both red light (630 to 680 nanometers) for skin benefits and near-infrared (800 to 830 nanometers) for deeper tissue treatment. This combo gives you the best of both worlds: surface-level improvements like collagen stimulation plus deeper healing for muscles and joints

• Irradiance: Irradiance refers to how much light energy is delivered to your body. "When it's too weak, it won't make much impact. Too strong, and it could be uncomfortable," says Lopez. "It's about finding the sweet spot backed by reliable research." That means, look for a device with irradiance levels between 20 an 200 mw/cm². This is generally considered safe and effective. Be wary of manufacturers making outlandish power claims — third-party verification is your friend here.

• Size and coverage area: Match your device to your goals. Full-body treatment calls for a larger panel or system, while targeted therapy for your face or specific problem areas might only need a compact device or mask. Larger devices pack more power and efficiency but demand more space and investment. Consider where you'll use and store your device — that sleek full-body panel might seem perfect until you realize it doesn't fit in your bathroom.

• Treatment time: Most effective protocols require 10 to 20 minutes per session, three to five times weekly. While that might not sound like much, it adds up. Devices with higher irradiance levels often cut down treatment time, making them more practical for busy schedules. Consider what fits into your routine. Even the most powerful device won't help if you can't make time to use it.

• Ease of use: You’re more likely to use a device regularly if it’s intuitive and comfortable. Some panels have adjustable stands or wall mounts, while others require awkward positioning. Masks should be lightweight and breathable. Handheld devices should feel ergonomic and not strain your wrist after a few minutes. And if the device feels like a hassle, it’ll end up in a drawer. Look for tools with straightforward controls, timers and safety features like automatic shut-offs.

• Portability and storage: If you travel often or want to bring your red light device between home, the office or even the gym, opt for a compact and lightweight model. Some portable options even come with travel cases to make it easier to bring with you. That said, if red light therapy is going to be a permanent part of your routine and you have the space, a larger panel or mounted system may deliver better and faster results.

• FDA registration and safety features: Our experts acknowledge that being FDA-registered doesn't guarantee a product works, it does show that the device meets basic safety standards for at-home use. This is especially important if you’re using the device on sensitive areas like your face or scalp. You should also look for built-in safety features like built-in timers or eye shields, and always follow the manufacturer's guidelines.

How we chose

To find the devices that truly deliver results, we spoke with three leading experts — a functional and integrative medicine physician, a nurse practitioner and a photobiomodulation researcher — to learn how light therapy works its magic at the cellular level. Their expertise helped illuminate (pun intended) what really matters in a quality device.

Armed with this knowledge, we explored over two dozen popular red light therapy devices, focusing on those offering both red and near-infrared light at scientifically proven wavelengths. We then spent four months testing 10 devices, evaluating everything from how they felt against our skin to how well they held up with regular use. While not every device earned a spot in our final recommendations, we made sure to cite other solid options that deliver effective treatment.

Other products we researched

There are a lot of great red light therapy devices on the market. The following didn't make the winners list either because I haven't yet tried them or they're not as versatile as some of the options that did. That said, these are reputable brands that use clinically proven therapies and wavelengths.

• Bon Charge Red Light Therapy Blanket: Red light therapy blankets are fairly new to the market. This one combines clinically backed levels of red and infrared light and has 360-degree coverage at a steep price of $1,999.

• MitoMAX Red Light Therapy Device: This sturdy flat panel has great power with clinically-backed red and infrared wavelengths. It's a good option for those looking for a slightly less expensive model than our best overall pick ($750).

• PlatinumLED BIO Series: Another flat panel option, this one is known for high irradiance and professional-grade performance, but it's bulkier than some other available options. (Prices start at $399)

• Megellin Red Light Therapy Bag: This pricey ($1,499) light-infused sleeping bag offers full-body coverage — or you can lay it flat for two people to use at once.

• LightStim for Wrinkles: The LightStim wand, priced at $249, is specifically designed for facial anti-aging benefits, but the smaller treatment area makes it less convenient than red light masks.

• Solawave Wand: A bargain at $135, this may be the best red light therapy wand for newbies. It's a good option for those who want something for spot treatment instead of full-face coverage.

• HigherDose Red Light Hat: Designed for hair growth, this wearable has 120 LED bulbs spread throughout and uses 650-nm red light wavelengths to target your scalp. Some studies suggest this wavelength can stimulate hair follicles and improve hair thickness over time. At $499, it may be worth a try for some.

FAQs

What strength is best for red light therapy?

The most effective devices emit red light between 630 and 680 nm and near-infrared light between 800 and 830 nm, according to Demchak. You also want to consider irradiance, better known as the power output. Think of it like your morning coffee: You want it strong enough to work (at least 20 mw/cm²) but not so strong or you'll feel the negative impact (keep it under 200 mw/cm²). The right strength depends on what you're treating and how deep you need that light to go.

Are there any side effects to red light therapy?

Good news: Red light therapy is generally gentle on your body. While some folks might notice a bit of redness or warmth, that's usually temporary and nothing to worry about. Lipman always suggests starting slow and sticking to the device's guidelines, just like you would with any new workout routine. Skip the sessions if you're pregnant, running a high fever or have a pacemaker. And if you've got darker skin, have a chat with your dermatologist first — they can help you avoid any unwanted dark spots.

Is red light therapy effective for pain management?

Yes. Demchak, for one, praises red light therapy as an effective treatment for acute and chronic pain. At the cellular level, it stimulates healing, reduces inflammation and improves circulation. It also regenerates cells and increases collagen production to repair damaged tissue, while boosting cell energy production that can trigger pain-relieving endorphins. Plus, as Demchak explains: "Pain signals travel from the injury site to the brain on nerves, but a high dose of light can decrease nerve conduction [thereby reducing pain].

How quickly can I expect results?

Some people start experiencing changes in their skin tone and inflammation in about two weeks. But for bigger projects, like easing joint pain or encouraging hair growth, Lopez says it'll likely take four to six weeks of consistent use before you notice anything. The key word here is "consistency." Stick to your device's recommended schedule and you'll be more likely to see the results that you're seeking.
