Our top picks for the best red light therapy devices for home use:
Best for full body: RedDot LED RDPRO6000 FS — highest output and coverage for whole-body use
Best for face: Lumara Red Light Mask — designed specifically for skin, anti-aging, and ease of use
Red light therapy (RLT) makes bold promises: just a few minutes a day under red or near-infrared light can reverse aging, reduce pain, and treat a surprisingly wide range of conditions. And with high-quality devices now available for home use, it’s easier than ever to try it yourself.
But does it actually work — and is it safe?
We partnered with Dr. Michael Hopkins, PhD, to find out. This guide is our attempt to answer three critical questions based on real scientific evidence:
Does red light therapy actually provide a benefit, and if so, what is it?
Is red light therapy truly safe, without possible negative side effects?
If you want to get a red light device, which one should you buy?
What Is Red Light Therapy?
Red light therapy (RLT) has been around since the 1960s. It uses specific wavelengths of light to treat skin and soft tissue conditions.
The idea is simple: when your skin is exposed to the right wavelengths and intensities of light, your cells start working better — healing faster, reducing inflammation, and repairing damage.

Our Research on the Best Red Light Therapy
Here’s the surprising thing about red light therapy: almost every claimed benefit is backed by real science.
We worked with Dr. Michael Hopkins, PhD, to sort through the research. His report was so thorough it ran dozens of pages.
The bottom line: after reviewing hundreds of pages of data, Dr. Hopkins found clear, well-supported benefits to RLT. The catch? The equipment you use matters — it needs to be independently tested and certified.
In this guide, we’ll help you understand what RLT can (and can’t) do, how to use it safely, and how to choose the right device.
Dr. Hopkins now uses his own red light therapy device for 10-20 minutes several times a day. He's seen an improvement in skin tone and wrinkles.

The Bottom Line on Red Light Therapy
Red light therapy (RLT) uses specific wavelengths of red and near-infrared light to help cells work better — healing faster, reducing inflammation, and repairing damage. Almost every claimed benefit is backed by real science, according to Dr. Michael Hopkins, PhD, who reviewed hundreds of pages of research.
The bottom line: RLT has clear, well-supported benefits — but the equipment matters. Devices need to be independently tested and certified.
Red light therapy has exploded in popularity — and so have the brands selling devices. Some manufacturers do things right: they test their products at independent labs and back up their claims with data. But many others make wild promises with no credible research to support them.
When we evaluated brands like Lumebox, Mito Red Light, Joovv, Hooga, and Celluma, Dr. Hopkins used four key criteria:
The specific wavelengths of light used
The irradiance (power density) of the device
The electromagnetic fields (EMF) produced
The amount of flicker — both should be as close to zero as possible
He also looked at manufacturer credibility: transparency of specs, FDA clearance, and third-party testing.
Energy Output: Irradiance & Radiant Exposure
The "strength" of a red light device is measured in mW/cm², also called irradiance. Based on the research Dr. Hopkins reviewed, effective treatments typically fall between 10 and 200 mW/cm².
To calculate your dose: multiply the irradiance by your exposure time in seconds. (One watt = one Joule per second, so some brands report dosage in Joules/cm² instead.)
One important catch: the industry standard for measuring irradiance is flawed. Most brands use Solar Power Meters, which are designed for white light — not red or near-infrared. This inflates their irradiance numbers. The accurate tool is a Laser Power Meter, which is expensive and rarely used.
Bottom line: Always look for brands with third-party lab testing. If a brand acknowledges this measurement problem and corrects for it, that's a strong credibility signal.
The Best Red Light Wavelengths
Dr. Hopkins found that the most effective wavelengths are 630nm and 650nm (visible red) and 830nm and 850nm (near-infrared).
630nm is better studied for skin tone, collagen, and elastin
660nm may have a stronger effect on ATP (cellular energy) production
Near-infrared (NIR) penetrates deeper — better for joint pain, muscle recovery, and conditions below the skin surface
The optimal therapeutic window is 600–1100nm (Rojas & Lima, 2011). Light below 600nm doesn't penetrate tissue well; light above 1100nm is absorbed by water before it can do much.
Bottom line: Look for a device that hits those wavelengths within ±15nm. If it doesn't, choose one with a broader range of frequencies rather than just one red and one NIR wavelength.
Our Top Pick: Best Red Light Devices
After researching dozens of red light devices and writing multiple versions of this guide, we found one brand that meets every standard we set. By going direct, we've made it the most affordable option at this quality level. Meet Gimme Red Light.
RedDot LED | RDPRO1500 | Red Light Therapy Panel
We vetted these panels against the strictest red and near-infrared light specs on the market — wavelengths, irradiance, EMF, and flicker. We're proud to carry them.
I have both the Mito mask and the LUMEBOX. Both use the gold-standard wavelengths for anti-agind — around 660nm red and 850nm NIR. The mask also offers other light modes for acne and skin concerns, but I’ll focus on anti-aging here.
Here’s how I think about the difference:
LUMEBOX: Very high irradiance up close (≈140 mW/cm² at contact), but it drops quickly with distance. You also have to move it around to cover your whole face (it won’t reach the sides if you just hold it straight in front of you). That said, it’s the most powerful option if you don’t mind holding it close to specific areas (forehead lines, joints, etc.). I use it 3–5 times a week, and because it’s so strong, even fewer sessions can make a difference.
Mito mask: Still high irradiance, but even coverage across your whole face since it sits much closer to your skin. More convenient than the box, but slightly less powerful, so you’ll want to use 3-5 times a week conistently.
Okay Stuff
Okay Red Light Brands
These brands are likely to be effective, but are only in the Okay Stuff category because: a) Dr. Hopkins was unable to confirm their efficacy as of this writing and/or b) they lack the proper certifications. For that reason, we recommend the brands above instead, but as we get more information we may move some of these brands up into the Good Stuff category.

Note: Hooga wrote to us complaining about their designation as Sneaky Stuff. We responded as follows: “We marked Hooga as Sneaky Stuff because irradiance measure reported on website says over 100mw/cm^2 and doesn’t give any distance–so presumably that is at 0cm. Irradiance should be given at a stated distance from the source- with these products usually 6-12″ away. Also, Hooga doesn’t have FDA clearance. Lastly, they have only 2 wavelengths of light and the Good brands generally have 3 or 4 wavelengths. If you want to update your website to provide source data and explain the instruments used to obtain your results, then you should do that for transparency and to be removed from Sneaky (but still likely only Okay Stuff).”We have not received a response.

What about Megelin? I was looking to get the EMS toning leggings and vest and the vitalux laser and therapy wear for a friend that has cancer but was unsure if this product is worth the high price? These are sensitive areas so always best to ask the best! I do already own the Mito light I bought off your site but wanted something more direct and easy to wear for my friend.
Thank you!

I have read everything you have posted, but I don’t see anything on using it if you have melanoma. I had it cut out of my cheek. There’s a significant scar and heard that you shouldn’t use red light if you have cancer. is this true?

Can you please compare these to red lights in spas/ wellness centers? And, could you also rate those commercial machines? Thanks
Red light therapy uses low-wavelength red light to penetrate the skin and stimulate cellular energy production, promoting healing, reducing inflammation, and improving skin health.
Look for devices with clinically studied wavelengths (typically 630–850nm), adequate power output (irradiance), third-party testing, and the right form factor for your treatment area.
Most experts recommend 3–5 sessions per week, with each session lasting 10–20 minutes depending on the device and treatment goal.
Safety & Wavelengths
Yes, when used as directed. Look for devices that are independently tested and certified. Always avoid looking directly into the lights.
Red light (630–700nm) primarily targets surface skin concerns, while near-infrared light (700–1100nm) penetrates deeper into muscles and joints for recovery and pain relief.
Usage & Applications
Yes! Devices like masks and panels are designed for facial use and can help with anti-aging, acne, and skin tone.
