The Health Benefits Of Using A Red Light Therapy Panel: A Complete Guide
Red light therapy is quickly becoming one of the most popular wellness modalities used for skin health, thyroid support, injury recovery, and overall wellness. Whether you’ve seen a red light therapy panel used in dermatology clinics, wellness centers, or paired with tools like an infrared sauna blanket or PEMF mat, there’s a reason this non-invasive therapy is exploding in popularity. And it is now even widely used in home.
Below is a full breakdown of what red light therapy is, how it works, and the many red light therapy benefits supported by research — including the latest findings on red light therapy for thyroid health.
What Is Red Light Therapy?
Red light therapy (also called photobiomodulation) uses therapeutic light energy from specific wavelengths of red and near-infrared wavelengths to stimulate healing at the cellular level.
Unlike UV rays or harsh blue light therapy, red and near infrared light do not damage the skin. Instead, they penetrate the skin and subcutaneous tissue to influence the mitochondria — the “powerhouse” responsible for producing cellular energy (ATP).
Common Red Light Therapy Devices
- Large panels (whole-body treatment)
- Red light therapy mask (targeted facial use)
- Smaller red light devices for travel or small areas
- Medium size that is perfect for daily use.
These come in many sizes and power levels. Some of the best red light therapy panels offer high irradiance, multiple wavelengths, and meet strict manufacturing and safety standards.
The Panel That I Use & Recommend
There are many red light therapy devices on the market. I have done hours of research on the best panels out there. The reality is that many of them are massively overpriced and/or don’t emit the correct wavelength. The panel that I use personally and recommend is the Red Light Therapy BQ60 from Bestqool. Not only is this device one of the most affordable on the market. But it is a professional red light therapy device with 660nm and 850nm LEDs which is the exact wavelength that much of the research that I share in this article is based on.

When we bought ours, we were so impressed with the price (compared to other panels on the market) that we wanted to make sure it was exactly what was advertised. So my husband brought the device to his work to test the wavelength and power using a spectrometer and power meter. And everything checked out! The power and wavelengths are exactly what is advertised.
How It Works: Mitochondrial Rejuvenation
The key mechanism behind the therapeutic benefits is mitochondrial stimulation. Red and near-infrared wavelengths increase ATP production, improve blood flow, enhance antioxidant defenses, and decrease inflammation — all of which translate into improvements you can feel and see.
This deeper, cellular activity is why RLT supports everything from fine lines and skin conditions, to joint pain, chronic pain, hair loss, and thyroid function.
The Top Health Benefits of Using a Red Light Therapy Panel
1. Enhances Skin Health and Reduces Signs of Aging
One of the most popular uses of a red light therapy device is improved skin health and skin rejuvenation.
Benefits:
- Boosts collagen production for firmer skin
- Reduces fine lines and wrinkles
- Improves skin tone and texture
- Helps fade dark spots and scars
- Promotes faster wound healing
- Improves hydration and elasticity
If you aren’t convinced yet, there is some pretty convincing research that demonstrates all of these skin benefits, such as this randomized, controlled trial with 136 volunteers, which showed that treatment with red and near-infrared light (twice a week for 30 sessions) significantly improved skin complexion, reduced fine lines and wrinkles, and increased intradermal collagen density.
Because this is a non-invasive treatment, many people use a panel as part of their daily routine for ongoing skin maintenance.
2. Reduces Inflammation and Chronic Pain
Red light therapy is widely used for pain relief, especially for people struggling with:
- Joint pain
- Tendon or ligament injuries
- Muscle strains
- Post-exercise soreness
- Systemic inflammation
- Long-term chronic pain
A recent review of low-intensity LASER and LED photobiomodulation in musculoskeletal conditions showed that PBM “reduces inflammation and swelling” and provides “pain relief … in non-specific knee pain, osteoarthritis, low back pain, etc.”
By calming inflammatory pathways and boosting cellular energy, RLT supports faster recovery and may improve mobility.
3. Speeds Up Muscle Recovery and Improves Performance
Athletes often use red light treatment for:
- Decreased muscle soreness
- Faster recovery between workouts
- Enhanced strength and performance
- Reduced oxidative stress
- Improved circulation to the treatment area
For those with specific goals like improved endurance, performance, mobility, or tissue repair, consistent use delivers better results.
4. Supports Thyroid Health (Research-Backed)
This is one of the most exciting and fast-growing areas of red light research.
Studies on photobiomodulation and low-level light therapy have shown potential benefits for people with hypothyroidism — especially Hashimoto’s. In this randomized, placebo-controlled clinical trial on patients with chronic autoimmune thyroiditis (Hashimoto’s), 10 sessions of LLLT (830 nm) led to a significant reduction in levothyroxine dose, lower TPO antibodies, and improved thyroid echogenicity.
A much larger study (350 patients) found that photobiomodulation significantly increased the T3/T4 ratio, reduced TPO antibody levels, and decreased the need for thyroid hormone replacement (LT₄)
Research such is this suggests red light therapy may help:
- Reduce thyroid-related inflammation
- Support improved T3/T4 conversion
- Improve tissue healing around the thyroid
- Potentially reduce thyroid antibody levels in some cases
- Support overall hormonal balance
Because the thyroid sits close to the skin’s surface, near-infrared light therapy can reach the gland, influencing cellular repair and reducing oxidative stress.
Important:
People taking thyroid medication should never adjust drug administration on their own. Always work with a qualified health professional or healthcare provider when using RLT for thyroid-related medical conditions.
5. Improves Sleep and Helps Regulate Circadian Rhythm
Red wavelengths support healthy melatonin levels — unlike UV light or blue light from bright lights, which can suppress melatonin.
Benefits:
- Helps you fall asleep more easily
- Supports deeper sleep
- Enhances mood and morning alertness
Many people combine their panel with an evening daily routine for calming, restorative sleep.
6. Reduces Joint Pain and Supports Mobility
Red light therapy is often used for joint conditions such as:
- Osteoarthritis
- Knee pain
- Hip or shoulder inflammation
- Post-injury stiffness
By increasing circulation and reducing inflammation, it’s an effective treatment option that’s easy to use at home.
7. Supports Hormone Balance and Fertility
While more research is needed, cellular stimulation from red and NIR light may help:
- Support reproductive tissue health
- Improve circulation
- Reduce inflammation
- Support mitochondrial energy in hormone-producing glands
This is why many use a red light device as part of a general wellness protocol.
8. Enhances Mood and Cognitive Function
RLT’s ability to influence cellular energy can also support the nervous system.
Benefits:
- Improved mood
- Reduced stress
- Clearer thinking
- Better emotional balance
Some users combine their panel with mindfulness practices for synergistic effects.
9. Promotes Hair Growth and Reduces Hair Loss
One of the most studied benefits of red light is its effect on hair follicles.
Benefits:
- Stimulates regrowth
- Thickens hair strands
- Reduces shedding
- Improves density over time
Many people use panel-based or cap-based devices to target hair loss, but panels work well for scalp coverage due to larger treatment area.
10. Supports Healthy Aging and Longevity
Because RLT works at the cellular level, it supports whole-body vitality.
Longevity-related benefits:
- Better mitochondrial function
- Reduced oxidative stress
- Improved metabolic balance
- Support for weight loss as part of a health regimen
- Strengthened cellular resilience
The transformative effects of red light therapy come from supporting the body’s natural repair processes.
Is Red Light Therapy Safe?
Red light therapy is considered very safe when used correctly.
Safety notes:
- RLT does not use UV rays, so it does not cause photoaging
- Wear eye protection if your device manual recommends it
- If you have photosensitivity or implants, consult a professional
- Always follow manufacturer usage guidelines
Side effects are rare and may include mild warmth or temporary redness.
How Often Should You Use a Red Light Therapy Panel?
For optimal results:
- 10–20 minutes per area
- 3–6 sessions per week to start
- Adjust based on specific needs and sensitivity
- Consistency creates the best results
If you’re new, start slowly and gradually increase treatment time.
