For a technology that involves doing absolutely nothing but basking in some light rays, red light therapy (RLT) is wildly effective.
Whether you're treating acne, thickening hair, softening fine lines, speeding muscle recovery, or just looking to biohack your way to a better mood, red light has entered the chat. Once reserved for dermatologists and expensive med spas, at-home RLT devices now come in all shapes, sizes, and wavelengths.
What makes red light therapy so powerful? It works at the cellular level, stimulating mitochondria (the energy powerhouses of your cells) to produce more ATP (adenosine triphosphate), the fuel your body uses to repair itself. That translates to brighter skin, faster muscle recovery, and even improved sleep.
Studies suggest stacking red light therapy with methylene blue -- yes, that vivid blue liquid with fans including RFK Jr. going viral for its nootropic benefits -- can supercharge results by enhancing mitochondrial function even further. Think of it as adding rocket fuel to your already glowing engine.
So whether you're a fitness junkie, a skincare maximalist, or just want to look hotter and live longer (don't we all?), here are the best red light therapy devices worth investing in -- plus one that's small enough to fit in your carry-on but mighty enough to turn your skin into a glazed donut.
Red light therapy (RLT), also known as low-level laser therapy (LLLT) or photobiomodulation (PBM), is a non-invasive treatment that utilizes specific wavelengths of red and near-infrared light (typically between 600 and 1000 nanometers) to stimulate cellular activity. This light penetrates the skin and is absorbed by the mitochondria -- the energy-producing components of cells -- enhancing the production of adenosine triphosphate (ATP).
Increased ATP production can improve cellular function, promoting healing and regeneration. Clinical studies have demonstrated that RLT can aid in skin rejuvenation, reduce inflammation, alleviate pain, and support hair growth. For instance, research has shown that RLT can effectively treat conditions like acne vulgaris and androgenetic alopecia, and improve skin texture and tone.
While RLT shows promise in a number of therapeutic areas, it's important to note that its efficacy can vary depending on the condition being treated and the levels of the therapy, such as wavelength, dosage, and treatment duration. Some studies have reported benefits in muscle recovery and pain reduction, particularly in conditions like knee osteoarthritis. However, more extensive and standardized clinical trials are needed to fully establish optimal treatment protocols and long-term safety.
Additionally, while we love an at-home RLT device since they are widely available and considered safe, they may be less powerful than professional-grade equipment. And, of course, as with any therapeutic treatment, it's advisable to consult with a healthcare professional before starting RLT to ensure it's appropriate for your specific health needs.
Don't let the size fool you -- the Gleam Mini is a professional-grade red and near-infrared light device disguised as a handheld glow stick. It uses medical-grade LEDs to deliver 660nm (red) and 850nm (near-infrared) wavelengths, scientifically proven to boost collagen, improve skin tone, reduce inflammation, and relieve pain at the muscular level. Most handheld RLT devices either skimp on power or go full-on toaster oven, but this one strikes the perfect balance between strength and portability.
Gleam is also FDA-cleared, shockingly lightweight, and wireless -- so yes, you can hold it to your face while binge-watching The Bear or angle it over your hip flexor after a savage Pilates class. The Gleam Mini has a built-in timer and auto-shutoff (a blessing for the forgetful), and the sleek magnetic stand means you don't need a third arm to use it.
I've been using the Gleam Mini every morning for the past two weeks, and not to be dramatic, but I think it's restructuring my face.
I use it for five minutes on each cheekbone (hello, glow) and then aim it at my jawline, where I tend to both break out and clench from stress. It’s warm, soothing, and weirdly meditative. My skin is visibly calmer and smoother, and I swear my jaw pain has eased. Also, it fits in my tote, so best believe it comes with me on my weekends away.
- Type: Cordless handheld device
- Time Commitment: Start with 1-2 minutes per area, gradually increasing to 10 minutes per session at a distance of 6-12 inches
- Results: 2-4 weeks of consistent use
If your primary goal is to channel your inner beached seal, the CurrentBody Skin LED Mask is a derm-favorite for a reason. This silicone mask molds to your face like a second skin and uses clinically proven red and near-infrared wavelengths to improve elasticity, smooth fine lines, and reduce redness. It’s hands-free and fits flush against the skin, which means more effective absorption and a spa-like experience without the $200 facial.
This is the mask you’ve seen all over TikTok (including on A-list celebs who pretend to be low-maintenance). It’s gentle enough for daily use, with results visible in as little as four weeks — and it doesn’t make you look like a cyborg with rage issues, which is nice.
- Type: Flexible silicone face mask
- Time Commitment: 10 minutes per session, 3-5 times per week
- Results: Within 4 weeks
Finally -- a wearable red light device designed for more than your cheekbones. The Kineon MOVE+ Pro is a modular, strap-on device built to deliver red (650nm) and near-infrared (808nm) light therapy directly to joints, tendons, and muscle groups, making it ideal for knees, shoulders, ankles, or even wrists. It’s wireless, rechargeable, and completely portable, so you can wear it during work, rest, or while plotting your revenge on whomever caused your tendinitis.
Unlike most wraparound devices that deliver weak surface light, the MOVE+ Pro uses laser diodes and LED combinations to penetrate deeper tissues and reduce inflammation where it actually starts. If you’re dealing with chronic pain, sports recovery, or even arthritis, this is a legit wearable solution—not just red light cosplay.
- Type: Cordless, modular wearable device
- Time Commitment: 5-15 minutes per session, once or twice daily
- Results: 2-4 weeks of consistent use
Hair thinning? Scalp inflammation? Low-level laser therapy (LLLT) is one of the few scientifically backed methods to stimulate hair regrowth and improve scalp health without relying on minoxidil or panic-buying hats. The Mito Red Light Professional Laser Therapy Helmet uses 200 diodes and a combination of red and near-infrared light to improve circulation and cellular regeneration at the follicular level.
It’s FDA-cleared, hands-free, and comfortable enough to wear while scrolling, emailing, or spiraling in silence on your couch. With consistent use (think 3 times per week, 20 minutes per session), studies show LLLT may help restore hair density and quality—especially for androgenic alopecia. You won’t see results overnight, but with patience, this helmet can quietly change the game—no greasy serums required.
- Type: Cordless helmet
- Time Commitment: 12-minute sessions every other day
- Results: Within 3-6 months of consistent use

What does red light therapy actually do?
Red and near-infrared light penetrates the skin and stimulates mitochondrial function to produce more adenosine triphosphate (ATP), boosting cellular regeneration and reducing inflammation. This helps improve skin tone, muscle recovery, and even mood.
Is red light therapy safe?
Yes, red light therapy is considered safe when used as directed. Most high-quality devices are FDA-cleared and emit wavelengths that do not damage DNA or cause burns. However, protective eyewear is recommended when treating areas near the eyes.
Can I use red light therapy with methylene blue?
Methylene blue can enhance mitochondrial activity and may synergize with RLT when used carefully. It acts as a redox agent and can improve the electron transport chain function when activated by light. However, consult a healthcare provider before combining the two.
How often should I use a red light therapy device?
Most studies suggest that 3 to 5 sessions per week, lasting 10 to 20 minutes, are beneficial for the skin. Muscle recovery may benefit from daily use depending on intensity. Always follow manufacturer guidelines.
What's the difference between red light and near-infrared light?
Red light (around 660nm) targets the surface of the skin -- great for treating wrinkles and acne. Near-infrared light (around 850nm) penetrates deeper into tissue and muscle helping with joint pain and recovery.
Is there a difference in the quality of red light therapy devices?
Absolutely. The RLT market ranges from sketchy Amazon gimmicks to professional-grade equipment used in clinical settings. Here's how they differ:
