Red Light Therapy for Skin & Mood: Benefits, Uses & Real Results (2025)

Red light therapy (RLT) might sound like something straight out of a sci-fi movie, but it’s very much a real and scientifically backed treatment. Essentially, red light therapy involves exposing your skin to low levels of red or near-infrared light. Unlike ultraviolet (UV) light from the sun, which can cause skin damage, red light is completely safe and beneficial when used properly.

When your skin absorbs these wavelengths—typically in the 620 to 750 nanometer range—it stimulates various biological processes at the cellular level. It penetrates the skin and energizes your cells' mitochondria (the “powerhouses” of cells), boosting ATP (energy) production. This results in accelerated tissue repair, enhanced cell regeneration, and improved circulation.

Red light therapy isn’t just a passing wellness trend. It’s FDA-approved for certain uses and widely recommended by dermatologists and holistic practitioners alike. Whether you’re trying to get clearer skin, reduce inflammation, or boost your mood, this therapy could be the non-invasive solution you didn’t know you needed.

Brief History and Evolution

Although it feels cutting-edge, red light therapy actually has its roots in NASA research. Back in the 1990s, NASA scientists explored red light as a means to promote plant growth in space. During the process, they discovered it could stimulate wound healing in astronauts, leading to a surge of interest in its therapeutic potential here on Earth.

Since then, RLT has made its way from high-tech labs into everyday wellness centers and homes. Initially used by elite athletes for recovery, and by dermatologists for specific skin treatments, it has become increasingly accessible to the general public.

Today, red light therapy is available in forms ranging from large panel devices to compact handheld gadgets—even face masks you can wear while watching Netflix. Its journey from outer space innovation to skincare and mood booster is a fascinating testament to the power of scientific discovery and wellness convergence.

How It Works: The Science Behind the Light

So how exactly does shining red light on your skin make you feel and look better?

It all starts at the cellular level. When red light penetrates the skin, it targets the mitochondria. These cell organelles absorb the light energy and ramp up production of adenosine triphosphate (ATP), the molecule responsible for powering most cellular functions. With more energy, cells can perform tasks like repairing damage, producing collagen, and reducing inflammation more efficiently.

There’s also an increase in circulation, which means more oxygen and nutrients reach your cells. That improved blood flow is key to healthier skin and can even affect brain chemistry—more on that later.

Interestingly, red light therapy doesn’t heat the skin like a sauna or laser. Instead, it’s a low-level laser therapy (LLLT) or photobiomodulation therapy. This makes it gentle, non-invasive, and safe for nearly all skin types.

Benefits of Red Light Therapy for Skin

Stimulating Collagen Production

Let’s talk about collagen—the protein responsible for giving your skin that youthful bounce. As we age, our collagen production slows down, leading to sagging, wrinkles, and thinner skin. That’s where red light therapy shines (literally).

When red light penetrates your skin, it triggers fibroblasts (the cells responsible for producing collagen and elastin) to kick into high gear. The result? Plumper, smoother, more elastic skin. Over time, consistent sessions can lead to visibly firmer skin with fewer fine lines and wrinkles.

Unlike topical treatments that only affect the outermost layer of your skin, red light therapy works from the inside out. It enhances your skin's natural regenerative abilities without requiring chemicals, needles, or downtime.

Numerous studies have confirmed red light’s role in promoting collagen synthesis. One published in the Journal of Investigative Dermatology showed significant improvements in skin texture and elasticity after regular exposure to red light over several weeks.

So, if you’re after that “glow from within,” red light therapy could be your go-to. It's not magic—just good science working for your skin.

Treating Acne and Blemishes

Acne sufferers, rejoice! Red light therapy isn’t just for wrinkles—it’s a game-changer for breakouts, too. Unlike harsh topical treatments that can dry out and irritate sensitive skin, red light offers a gentle and effective alternative.

Here’s how it helps: Red light reduces inflammation, one of the biggest culprits behind acne flare-ups. It also helps to shrink sebaceous glands, which means less oil production—another major contributor to acne. In some cases, red light is combined with blue light therapy (which kills acne-causing bacteria) for a one-two punch against stubborn breakouts.

What’s especially compelling is that red light can heal post-acne marks and reduce redness. It accelerates the skin’s natural healing process, making it ideal for anyone dealing with both active acne and lingering scars.

Users often report that their skin feels calmer and less irritated after just a few sessions. And because it’s non-invasive and drug-free, it’s a great option for teens and adults alike.

Reducing Fine Lines and Wrinkles

Fine lines creeping in around your eyes or mouth? Red light therapy might be the answer you’ve been looking for.

As collagen and elastin levels dip with age, skin loses firmness and elasticity. Red light therapy reverses this process by encouraging the skin to regenerate and thicken. This leads to visible reductions in crow’s feet, smile lines, forehead creases, and other signs of aging.

Consistency is key here. Regular sessions over several weeks—often just 10-20 minutes each—can lead to long-term improvements. Think of it like a workout for your skin. The more you do it, the stronger (and younger-looking) it becomes.

Clinical trials support these claims, with participants showing smoother, more hydrated skin after eight to twelve weeks of red light treatments. Unlike Botox or fillers, red light therapy improves your skin’s health and appearance from within.

And the best part? You can do it from the comfort of your own home, no needles or downtime required.

Healing Scars and Sun Damage

Scars and sun damage can be more than just a cosmetic nuisance—they’re visible reminders of past skin trauma. Whether it’s acne scars, surgical marks, or hyperpigmentation from years of sun exposure, red light therapy offers a powerful, non-invasive way to help your skin recover.

Red light therapy boosts circulation and encourages your skin cells to regenerate more effectively. For scars, this means softer, flatter, and less visible tissue over time. For sun damage, red light therapy can help fade dark spots, improve skin tone, and restore a smoother texture.

What’s truly remarkable is that RLT can stimulate the production of new capillaries and repair damaged tissues, including those in deeper layers of the skin. Over several weeks of regular use, people often notice a reduction in discoloration and improved elasticity.

And it’s not just anecdotal. Clinical research has shown that red light therapy improves skin texture and pigmentation without harming surrounding tissue—unlike chemical peels or lasers. This makes it a great option for those with sensitive skin or anyone looking for gradual, natural healing.

If you’ve been hiding your skin under makeup or long sleeves, this therapy can help you feel more confident, no cover-up required.

Clinical Studies Supporting Skin Benefits

Let’s dive into the science behind the claims. Red light therapy is backed by an increasing body of peer-reviewed research that validates its effectiveness in skin rejuvenation and healing.

A landmark study published in the Journal of Photochemistry and Photobiology found that participants who used red light therapy experienced a significant improvement in skin tone, collagen density, and overall skin appearance after just four weeks. Another clinical trial from Dermatologic Surgery observed that regular RLT helped reduce wrinkles and fine lines in over 90% of participants.

Moreover, the American Journal of Clinical Dermatology reviewed multiple studies and concluded that low-level light therapy is effective for treating acne, photoaging, and even rosacea. What sets red light apart is that it provides all these benefits with minimal risk of side effects, making it suitable for nearly everyone.

These studies offer something more than anecdotal evidence—they provide the kind of credibility that makes both medical professionals and skincare experts take red light therapy seriously.

So if you’re still skeptical, remember: this isn’t just wellness hype—it’s real, proven science that’s transforming the way we care for our skin.

Red Light Therapy and Mood Enhancement

How Light Affects the Brain

Ever notice how you feel more energized on sunny days and sluggish when it’s gloomy? That’s because light has a direct impact on your brain chemistry. Red light therapy takes this principle and enhances it by using specific wavelengths that positively influence mood and mental well-being.

Exposure to red light stimulates the brain’s production of serotonin, often referred to as the “feel-good” neurotransmitter. It also helps regulate melatonin levels, improving your sleep cycle and reducing fatigue. Unlike harsh artificial lighting, which can disrupt your circadian rhythm, red light mimics the beneficial aspects of natural sunlight without the harmful UV rays.

The real magic happens in the hypothalamus, a brain region responsible for controlling hormones and emotional responses. Red light therapy can “reset” this system, especially when used regularly in the morning or early evening. That’s why many users report feeling more balanced, less anxious, and even more motivated after a session.

In short, it’s not just about looking better—it’s about feeling better, too. And who doesn’t want that kind of boost without popping a pill?

Combating Seasonal Affective Disorder (SAD)

If you’ve ever felt more depressed, lethargic, or unmotivated during the winter months, you’re not alone. Seasonal Affective Disorder, or SAD, affects millions of people every year. The cause? Reduced sunlight exposure disrupts your circadian rhythms and lowers your serotonin levels.

Enter red light therapy. Unlike traditional light therapy boxes that use full-spectrum light, RLT targets the wavelengths that directly influence mood and hormonal balance. It offers a gentler, more focused way to stimulate the brain’s natural chemistry and lift that heavy fog of seasonal blues.

Using red light therapy during the darker months—or even year-round if you work indoors or live in a cloudy climate—can help regulate sleep patterns, stabilize your mood, and reduce anxiety symptoms. Sessions as short as 10 minutes a day can make a noticeable difference in how you feel and function.

And it’s not just for diagnosed SAD sufferers. Many people use red light therapy proactively to prevent the winter slump before it starts. Think of it as emotional armor for those cold, dreary days.

Managing Anxiety and Depression Naturally

Let’s face it—modern life is stressful. Between work, social pressures, and endless scrolling, it’s easy to feel overwhelmed. While medication and therapy are important tools, many people are looking for additional, natural ways to manage anxiety and depression. Red light therapy is proving to be one of them.

By targeting the brain’s energy production and hormonal balance, red light therapy helps reduce cortisol (the stress hormone) and increase endorphins, the body’s natural mood elevators. It also encourages better sleep, which is a critical component of mental health.

Clinical trials have found that red and near-infrared light can modulate brain function in areas associated with emotional regulation, such as the prefrontal cortex. This has led to promising results in treating mild to moderate depression and generalized anxiety disorder (GAD).

What’s amazing is that these effects are cumulative. Like yoga or meditation, the benefits of red light therapy build over time, offering lasting improvements in mood and mental clarity. Best of all, it’s side-effect-free and can easily be integrated into your morning or evening routine.

User Testimonials and Psychological Studies

Nothing makes a case better than real-world results. Thousands of users around the globe are turning to red light therapy not just for skincare, but for the profound mental and emotional relief it offers.

Take Jane, a 34-year-old office worker who struggled with seasonal depression. After just two weeks of daily red light sessions in the morning, she reported increased energy, improved focus, and a general sense of calm she hadn’t felt in years. Or Mike, a veteran dealing with PTSD who found red light therapy helped reduce his anxiety attacks and improve his sleep.

Psychological studies back up these stories. A meta-analysis from the Journal of Affective Disorders concluded that low-level red light therapy shows statistically significant improvement in mood disorders compared to placebo.

This growing body of testimonials and clinical evidence paints a powerful picture: red light therapy isn’t just a beauty trend—it’s a legit, science-backed way to enhance your emotional well-being.

How to Use Red Light Therapy

Devices: At-Home vs Professional

One of the great things about red light therapy is its flexibility. Whether you're a busy professional, a stay-at-home parent, or someone who loves visiting wellness spas, there's a device or method that fits your lifestyle.

Professional Treatments: Clinics, dermatologists, and wellness centers often use high-powered red light panels or lasers that deliver concentrated doses of light. These professional-grade treatments are generally more intense and yield faster results, especially for skin rejuvenation or more serious conditions like scarring or rosacea. Sessions typically last 15–30 minutes and may cost anywhere from $50 to $200, depending on the provider and location.

At-Home Devices: The rise of portable red light therapy devices has changed the game. You can now buy everything from full-body panels and face masks to handheld gadgets for targeted treatment. These at-home devices tend to use lower light intensities, so they may take a bit longer to produce results, but they’re incredibly convenient and budget-friendly in the long run.

Popular options include:

• LED face masks (great for facial acne or wrinkles)

• Light therapy lamps (for mood and SAD)

• Red light therapy wands or panels (for spot treatment or full-body sessions)

Choosing between at-home and professional treatments depends on your goals, budget, and how quickly you want results. Many users even combine both approaches for optimal effectiveness.

Recommended Duration and Frequency

Like any wellness routine, red light therapy works best when you stick with it consistently. But what does that actually look like?

For Skin Benefits:

• Frequency: 3–5 times per week

• Duration: 10–20 minutes per session

• Timeframe: Visible results often appear within 4–8 weeks

For Mood and Energy:

• Frequency: Daily or at least 3 times per week

• Duration: 10–15 minutes, preferably in the morning

• Timeframe: Many users report mood improvements within 1–2 weeks

It's important to hold the device the correct distance from your skin—usually 6–12 inches depending on the manufacturer’s instructions—and avoid overdoing it. More is not always better. Overexposure could lead to skin irritation or reduced effectiveness due to light desensitization.

Consistency is key. You wouldn’t expect to hit the gym once and get abs, right? Same with red light therapy—it’s all about regular use for sustained benefits.

Safety Tips and Best Practices

Red light therapy is generally very safe, but like any treatment, it's important to follow best practices to avoid irritation or ineffective results.

1. Follow Manufacturer Guidelines: Every device has slightly different specifications for wavelength, intensity, and recommended use. Always read and follow instructions carefully.

2. Clean Your Skin Before Use: Red light penetrates best through clean, product-free skin. Remove makeup or lotions to maximize effectiveness.

3. Protect Your Eyes: While red light is not UV and doesn't damage the eyes like sunlight, direct exposure—especially with high-powered devices—can still be uncomfortable. Many devices come with goggles; use them.

4. Stay Consistent: Results aren’t overnight. Keep a treatment journal to track your progress and adjust your schedule as needed.

5. Don’t Overdo It: More isn’t always better. Stick to the recommended treatment times to avoid skin fatigue or light resistance.

If you're pregnant, have epilepsy, or take photosensitive medication, consult a healthcare professional before beginning therapy.

Red light therapy is a powerful tool—but only when used wisely.

Red Light Therapy for Different Skin Types and Conditions

Suitability for Sensitive Skin

If you have sensitive skin, you're likely cautious about trying new treatments—and with good reason. Many skincare products and procedures can cause irritation, redness, or flare-ups. The good news? Red light therapy is one of the few treatments that’s not only suitable for sensitive skin but often helps soothe it.

Why? Because red light reduces inflammation and improves cellular function without heat or chemicals. Unlike peels or lasers, it doesn’t remove layers of skin or cause trauma. That means it's gentle enough for people with eczema, rosacea, or dermatitis.

In fact, many dermatologists recommend RLT as a first-line option for sensitive skin issues because it can strengthen the skin barrier, enhance hydration, and reduce the appearance of redness over time.

Tips for using RLT with sensitive skin:

• Start with shorter sessions (5–10 minutes)

• Use low-intensity settings if available

• Space out sessions (e.g., 3x/week) to see how your skin responds

If your skin is easily reactive, do a patch test on a small area before committing to full-face or body sessions. You might be pleasantly surprised at how calming and healing red light therapy can be.

Treating Eczema, Psoriasis, and Rosacea

Skin conditions like eczema, psoriasis, and rosacea can be painful, persistent, and tough to manage. While there's no “cure,” red light therapy has emerged as a promising way to reduce flare-ups and improve quality of life.

Eczema: Characterized by itchy, inflamed patches of skin, eczema often involves a compromised skin barrier and overactive immune response. Red light therapy helps by reducing inflammation and encouraging the growth of healthy new skin cells. Over time, this can lessen itching, scaling, and redness.

Psoriasis: This autoimmune condition causes skin cells to build up rapidly, forming scaly, itchy patches. Red and near-infrared light has been shown to slow down cell proliferation and reduce inflammation, easing symptoms without the side effects of steroids or biologics.

Rosacea: Red light therapy calms the inflamed blood vessels that cause flushing and redness. Regular use can decrease sensitivity and flare-up frequency, especially when paired with a gentle skincare routine.

Unlike many topical treatments that only offer short-term relief, red light therapy works at a cellular level, providing more sustained improvements. And because it’s non-invasive, it can be a great complement to other treatments prescribed by your dermatologist.

Anti-aging for Mature Skin

Aging gracefully doesn’t mean giving up on your skin—it means giving it the care it needs to stay healthy and radiant. Red light therapy offers mature skin exactly that.

As we age, our skin produces less collagen and elastin, leading to sagging, fine lines, and a loss of volume. Red light therapy reverses these signs by jumpstarting your skin’s natural renewal process. It not only boosts collagen but also increases blood flow, enhances hydration, and even improves tone and texture.

In a clinical trial involving women over 50, red light therapy significantly improved skin firmness and reduced wrinkle depth after just eight weeks. Participants also reported smoother, more radiant complexions—without downtime or side effects.

For mature skin, red light therapy can:

• Reduce age spots and pigmentation

• Tighten loose skin on the face and neck

• Soften crow’s feet, frown lines, and laugh lines

• Improve skin density and resilience

It’s like pressing the “reset” button on your skin—naturally and effectively.

Comparing Red Light Therapy with Other Treatments

Blue Light vs Red Light

Both red and blue light therapies are popular in skincare, but they serve very different purposes. Knowing which one is right for you depends on your goals.

Blue Light Therapy primarily targets the surface of the skin and is incredibly effective at killing acne-causing bacteria (P. acnes). It’s often used for oily skin and acne-prone individuals. However, it can sometimes cause dryness or irritation, especially for those with sensitive skin.

Red Light Therapy, on the other hand, penetrates deeper into the skin to reduce inflammation, boost collagen production, and improve circulation. It’s ideal for aging skin, healing, and overall rejuvenation. Red light also helps reduce redness and improve tone—something blue light doesn’t directly address.

In many cases, the best solution is combining both: blue light for active acne, red light for healing and preventing scarring. This combo is a go-to for dermatologists treating acne and rosacea.

If you're looking for long-term skin health and anti-aging, red light therapy is the clear winner. If acne control is your priority, blue light might be your best starting point.

Laser Treatments vs LED Therapy

Red light therapy and laser treatments may seem similar—they both use light to treat the skin—but they’re fundamentally different in how they work and what they do.

Laser Treatments (like fractional lasers or CO2 lasers) use highly concentrated beams of light to remove skin layers and stimulate collagen production. They’re incredibly effective for treating deep wrinkles, scars, and pigmentation. However, they come with side effects like redness, peeling, and downtime, sometimes lasting weeks. They also tend to be more expensive and are often not suitable for all skin types, especially darker complexions.

LED Red Light Therapy, in contrast, uses a broader, less intense light that penetrates the skin without causing damage. It’s painless, non-invasive, and doesn’t require any downtime. It’s ideal for gradual improvements in skin tone, texture, and inflammation.

Here’s a quick comparison:

So, if you're seeking dramatic, fast results and are okay with downtime, lasers may be the route. But if you want safe, consistent improvement without side effects, LED red light therapy is a smart investment.

Natural Alternatives: How Does It Stack Up?

There are plenty of natural skincare solutions out there—aloe vera, vitamin C serums, facial massages, herbal tonics, and essential oils. While these options can certainly benefit your skin and mood, red light therapy offers something unique: cellular stimulation at a level that topical treatments can’t reach.

Most natural remedies work on the surface. They hydrate, soothe, or provide antioxidants. But red light therapy dives deep, energizing your mitochondria and prompting your skin to repair itself from the inside out.

Here’s how it compares to popular natural treatments:

• Vitamin C serums: Excellent for brightening skin, but they don’t stimulate collagen at the cellular level like RLT does.

• Facial oils: Great for moisture but do little for skin elasticity or deep healing.

• Meditation and exercise: Awesome for mood and circulation—but red light adds a biological boost through light-induced serotonin and melatonin regulation.

• Herbal remedies: Can reduce inflammation, but results are often subtle and slow.

Bottom line? Red light therapy doesn’t replace natural remedies—it enhances them. It’s the missing link between nature and science, offering a deeper, more foundational approach to both skincare and emotional wellness.

Side Effects and Risks

Common Concerns and Misconceptions

Red light therapy might seem too good to be true—clear skin, better mood, no downtime? Naturally, people have questions, and some skepticism is understandable.

Myth 1: “Red light can burn your skin.”
Not true. Unlike UV rays or lasers, red light therapy uses low-level light that doesn’t produce heat or burn. It’s actually classified as “non-thermal,” meaning it doesn't raise skin temperature significantly.

Myth 2: “It’s just a placebo effect.”
Nope. Red light therapy is backed by dozens of clinical studies and FDA approvals. It’s used in dermatology clinics, hospitals, and physical therapy centers worldwide for real, measurable benefits.

Myth 3: “You need to feel something for it to work.”
Another misunderstanding. Red light therapy often feels like… nothing at all. No tingling, burning, or pulsing. But the lack of sensation doesn’t mean it’s not working—your cells are still absorbing light and responding biologically.

Possible side effects? They’re rare and usually minor:

• Temporary redness

• Mild headaches (from very intense lights)

• Eye strain if used without protection

As long as you follow usage guidelines, red light therapy is considered one of the safest light-based treatments available.

Who Should Avoid Red Light Therapy?

Even though red light therapy is safe for most people, there are a few cases where caution—or avoidance—is advised.

1. Pregnant Women: There’s no conclusive research on red light therapy’s effects during pregnancy. While it’s likely safe, it’s best to consult a healthcare provider before starting treatment.

2. People on Photosensitizing Medications: Drugs like Accutane, tetracycline, or certain antidepressants can increase light sensitivity. Using red light during treatment may cause skin irritation or discomfort.

3. Those with a History of Skin Cancer: If you’ve had melanoma or another form of skin cancer, check with your dermatologist before using any light-based treatment—even non-UV red light.

4. People with Seizure Disorders: Intense flashing or flickering lights can be a trigger for some individuals with epilepsy, though red light therapy devices typically don’t flash.

Always consult your doctor before beginning red light therapy if you have underlying health conditions. While it’s incredibly safe for the majority, everyone’s body is different—and your health comes first.

Cost and Accessibility

Price Comparison: At-Home vs Clinics

When deciding whether to go for professional red light therapy or invest in an at-home device, cost is often a big factor. Both options have pros and cons, depending on your budget, lifestyle, and commitment level.

Professional Treatments at Clinics:

• Average session cost: $50–$150

• Typical frequency: 2–3 sessions per week for 8–12 weeks

• Total treatment cost: $800–$2,000+ for a full series

These treatments often use stronger medical-grade machines, which can yield faster results. They’re ideal if you’re looking for a quick fix or targeting a severe skin issue. Plus, you’ll benefit from expert supervision and tailored advice.

At-Home Devices:

• Handheld/red light wands: $100–$300

• Mid-range LED panels: $300–$600

• Premium full-body panels: $800–$2,000

While the initial cost of an at-home device may seem high, it’s a one-time investment that can save money in the long run. If used consistently, many at-home tools deliver comparable results to clinic visits—especially for skin maintenance and mood support.

If you're serious about long-term use, an at-home device is often the smarter financial choice. You can treat yourself anytime, anywhere, without commuting or booking appointments.

Is It Covered by Insurance?

Red light therapy is still considered an “alternative” or “complementary” treatment by most insurance companies. As a result, it’s generally not covered—especially if you're using it for cosmetic reasons like wrinkle reduction or acne treatment.

That said, there are exceptions. If your doctor prescribes red light therapy for medical conditions such as chronic pain, wound healing, or arthritis, some health insurance plans or Health Savings Accounts (HSAs) may reimburse part of the cost. In rare cases, flexible spending accounts (FSAs) can also be used to pay for red light devices or treatments with a doctor’s note.

If cost is a concern, here are a few tips:

• Ask your provider: Some wellness clinics offer financing or discounts for bulk sessions.

• Check for FDA-cleared devices: These have better chances of insurance reimbursement with medical documentation.

• Consider entry-level devices: You can find portable options that deliver effective results without breaking the bank.

Even if it’s not covered by insurance, the long-term value of red light therapy—fewer dermatologist visits, reduced product spending, and enhanced mental health—often makes it worth every penny.

FAQs

Is red light therapy safe for daily use?

Yes, red light therapy is safe for daily use, provided you follow the recommended exposure times. Most users benefit from 10–20 minute sessions 3–5 times per week. Overuse doesn’t increase benefits and can sometimes irritate sensitive skin.

How soon can I see results with red light therapy?

Many people see subtle changes within the first 2 weeks, such as brighter skin and improved mood. For more dramatic improvements like wrinkle reduction or acne clearing, consistent use for 8–12 weeks is typically needed.

Can red light therapy help with sleep?

Absolutely. Red light helps regulate melatonin production, which can improve sleep quality. Using it in the evening, especially on the face and chest, signals the body to wind down and promotes deeper rest.

Do I need to wear eye protection?

It depends on the intensity of your device. Low-level home devices may not require protection, but high-powered panels used close to the face should be paired with goggles to prevent eye strain.

What’s the difference between red light and infrared light?

Red light (620–750nm) targets the skin’s surface, while near-infrared light (750–1200nm) penetrates deeper into muscles and tissues. Both offer healing benefits, but infrared is more commonly used for joint pain and muscle recovery.
