Knowledge Base & Resources Page: Red Light Therapy (Photobiomodulation)
Welcome to our knowledge base on red light therapy (also known as photobiomodulation, PBM). We value transparency. That’s why we support our health claims only with real, published, and peer-reviewed studies, preferably from reliable medical databases such as PubMed and NCBI.
Red light therapy is not a magical concept. Study results strongly depend on factors such as wavelength (red vs near-infrared), dosage, treatment duration, and the measured outcome.
On this page, you will find an overview of scientific studies by topic, so you can read for yourself what has and sometimes has not been demonstrated in the literature.
Red light therapy for muscle and joint pain
Scientific research shows that red light therapy reduces pain, inhibits inflammatory processes, and speeds up the recovery of muscles and joints by stimulating mitochondrial activity and improving blood circulation.
"Red Light Therapy accelerates muscle recovery and reduces muscle soreness after exercise"
A systematic review and meta-analysis of 14 studies examined the effect of photobiomodulation on muscle soreness after intense exercise. The results show that red light therapy significantly reduces muscle soreness at 72 and 96 hours post-exercise, and muscle strength recovers faster at 24 and 48 hours — compared to a placebo treatment. Photobiomodulation can therefore be an effective tool for athletes and active individuals who want to recover faster after intense training.

The recommended duration of a session is usually between 10 and 15 minutes at a distance of 50 cm. At a longer distance, you can sit a bit longer behind the lamp, about 15 - 20 minutes at 100 cm.
It is generally recommended to maintain a distance of 30 - 50 cm from the lamp. However, some products, such as LED face masks, can be used closer to the skin. For products that require a different distance, this is clearly stated on the product page. Want to know more?
Although there are no strict rules, regular use is recommended. Start with 2 to 3 sessions per week to let your body get used to it. Listen carefully to your body.
You can gradually adjust the number of sessions based on your comfort level. For the best effect, at least 4-6 times per week is recommended.
Red light and near-infrared light (NIR) penetrate deeply into the skin and are absorbed by the cells.
Light in the red and NIR spectrum can penetrate the skin to a depth of about 5 to 10 millimeters, allowing it to reach deeper tissues.
Once inside the cell, the light is absorbed by the mitochondria, the powerhouses of the cell.
Mitochondria contain a light-absorbing enzyme called cytochrome c oxidase, which plays a crucial role in the production of adenosine triphosphate (ATP), the main energy source for cellular processes.
The absorption of light by cytochrome c oxidase stimulates the mitochondria to produce more ATP.
ATP is essential for numerous cellular functions, such as repair, regeneration, and normal cell operation. With more available energy, cells can work more efficiently and recover faster from damage.
Red Light Therapy increases ATP production and improves cellular functions, leading to accelerated tissue repair and regeneration. This results in faster wound healing, less scarring, and improved skin health.
The anti-inflammatory effects of photobiomodulation relieve pain, reduce swelling, and improve joint and muscle function. Additionally, the therapy supports the immune system, promotes muscle recovery, helps with chronic pain, and enhances overall energy and vitality.
No negative side effects are known, making it a safe option for a wide range of users. Additionally, our devices are easy to use and come with clear instructions for correct and safe application. Want to know more?
Maintaining a red light therapy panel is essential to ensure it functions optimally and has a long lifespan. Here are some tips for proper maintenance:
- Clean regularly with a soft, dry, or slightly damp cloth (no harsh cleaning agents).
- Avoid humid areas, such as the bathroom.
- Regularly check the cables and plugs for wear.
- Allow the panel to cool down after use.
- Follow the manufacturer's maintenance guidelines.
Red light and near-infrared light (NIR) are both forms of light within the electromagnetic spectrum, but they differ in wavelength and how they are absorbed by the body.
1. Wavelength
Red light has a wavelength between 600 and 700 nanometers (nm), and it is visible to the human eye. It has a warmer, more visible glow.
Near-infrared light has a longer wavelength of 700 nm to about 1,200 nm. This is just outside the visible spectrum, making it invisible to the human eye, but it still carries a lot of energy and can penetrate deeper layers of the body.
2. Penetration in the body
Red light penetrates the skin to about 5 millimeters deep. It is mainly used to stimulate the superficial skin layers, such as improving skin texture, collagen production, and reducing inflammation.
Near-infrared light can penetrate deeper, up to 2-3 centimeters into the body. It is often used for muscle recovery, joint pain, and improving blood circulation in deeper tissues.
3. Applications
Red light is often used for skin care and promoting healthy skin, for example by stimulating collagen production and reducing inflammation.
Near-infrared light is often applied for deeper tissue recovery such as muscle and joint pain, promoting blood circulation, and accelerating recovery after physical exertion or injuries.
4. Effects on the body
Both types of light have therapeutic effects, such as promoting cell repair and reducing inflammation. However, near-infrared has more impact on deeper tissues and is often used for pain relief, while red light is more focused on skin improvement and superficial regeneration.
In general, they are often used together in combination therapies to harness both the benefits of superficial skin improvement and deep tissue therapy.
Users of our panels notice improvements in pain relief, inflammation, and mobility within just a few days.
Our surveys show that 94% of customers experience pain relief within the first 4 weeks of regular use. Consistency is key for the best results.
