Red light therapy, also known as Red Light Therapy or photobiomodulation, is a natural form of light therapy that uses specific wavelengths of red and near Infrared light to support the body at the cellular level. The light penetrates deeply into the skin, muscles, and joints, supporting processes involved in energy production, recovery, and cell renewal.
This form of light therapy is used worldwide for muscle recovery, skin improvement, relaxation, joint support, and overall well-being.
Red Light Therapy is used worldwide for recovery, skin, and general well-being. These are the most common applications.
Supports the natural recovery of muscles after exertion and training.
Works as an anti-inflammatory and helps with stiffness and pain complaints.
Stimulates collagen production for firmer and more even skin texture.
Used to support joint and rheumatic complaints.
Promotes local blood circulation and oxygen supply in the tissue.
Helps the body to relax and recover after a busy day.

Red light therapy, also known as photobiomodulation or Red Light Therapy, is being researched worldwide for its potential support in recovery, skin improvement, and overall well-being. More than 3000 scientific publications and studies have now examined the applications of red and near Infrared light within health, sports recovery, and wellness.
Scientific studies mainly focus on the interaction between red light therapy and the energy production of human cells, including processes involved in ATP production, mitochondria, and natural recovery processes.
Photobiomodulation is the process by which specific wavelengths of red and near Infrared light are absorbed by the cells of the body. The mitochondria play an important role in this. These parts of the cell are responsible for the production of ATP, the body's main energy source.
Red light therapy uses specific wavelengths of light such as red light and near Infrared light. These wavelengths can penetrate deeply into the skin and muscles without using harmful UV radiation.
Red light therapy is widely used to support muscle recovery, relaxation, skin improvement (acne, psoriasis, etc.) and joint support. It is also often used in wellness, sports recovery, and daily recovery routines.
Unlike tanning beds, red light therapy does not contain harmful UV radiation. Modern red light therapy panels also produce only mild heat, making the treatment comfortable and widely applicable.
Discover how red light therapy works at the cellular level and why it is so effective for your health and well-being.
Red light (610/630/660 nm) and near-infrared light (810/830/850/940/1060 nm) penetrate your skin and reach the mitochondria, the energy factories in your cells. The deeper the light penetrates, the more cells are activated.
In your mitochondria, there is nitric oxide (NO) that slows down energy production by blocking oxygen. The light releases this block, allowing oxygen to do its work again. This core mechanism is called photobiomodulation.
ATP is the fuel of your cells. With the brake off, your mitochondria produce more ATP. More fuel means more capacity to recover, renew, and become stronger.
The extracellular energy initiates recovery processes that lead to less inflammation, faster muscle recovery, better sleep, improved circulation, collagen production, and support for rheumatic complaints and issues like osteoarthritis. Your body does what it naturally can, but more effectively.
Red Light Therapy is easy to use at home. The correct distance and session duration depend on what you want to treat: the skin or deeper tissues such as muscles and joints.
The distance determines how much light your cells receive. For skin improvement and general use, you usually keep a distance of 30 to 38 cm. For targeted treatment of muscles, joints, or skin repair, you sit closer, around 15 to 23 cm. The closer you are to the panel, the shorter the session needs to be, because the amount of light is then higher.
For the skin, a short session of 1 to 2 minutes per area is sufficient. For deeper tissues such as muscles and joints, you should allow 2 to 5 minutes per area. If you treat multiple areas, the total session duration usually comes to 10 to 20 minutes. More is not better: a higher dose than recommended adds little benefit.
For the best results, use red light therapy 3 to 5 times a week. Start gently with shorter sessions at a greater distance and gradually increase. If you want to treat more than once a day, leave at least 6 hours between sessions.
Many people look for an Infrared lamp for their muscles, while they are actually searching for Red Light Therapy. The difference is important. An Infrared lamp is a heat lamp that temporarily relaxes your muscles through warmth. Red Light Therapy works differently: it supports the actual recovery of your cells through specific wavelengths of light. One provides direct, short-term relief through heat. The other works on structural recovery.

Red Light Therapy
|
|
|---|---|---|
| Operation | Heats the tissue through thermal radiation | Stimulates cells through light (photobiomodulation) |
| Goal | Temporary relaxation of muscles | Supports structural cell repair |
| Golf lengths | Broad heat radiation, not specific | 8 specific wavelengths (red and near-infrared) |
| Effect after use | Disappears largely when the heat is gone | Builds up over time with repeated use |
| Heat generation | High, can become uncomfortable | Minimal, comfortable to use |
| Application | Muscle relaxation through heat | Recovery, skin, inflammations, muscles, and joints |
An Infrared lamp is a heat lamp that temporarily relaxes muscles through warmth. Red Light Therapy works through specific wavelengths of light (photobiomodulation) that stimulate your cells to repair themselves.
One provides short-term relief through heat, the other supports structural recovery.
Red Light Therapy contains no harmful UV radiation. It is wise not to look directly into the bright light during use. Many people close their eyes or use protective goggles during a facial session.
The result varies per person and per application. Many users notice a difference in skin improvement after 4 to 8 weeks. For muscle recovery, the effect can be felt even sooner. Consistent use is crucial for the result.
Yes, red light therapy is safe for daily use. It contains no UV radiation and is generally well tolerated. Many users build it into a regular routine.
Red Light Therapy is widely used by athletes to support muscle recovery. The near-infrared light reaches deeper tissues and supports the natural recovery processes after exertion.
Red Light Therapy is generally well tolerated and safe for most people when used correctly. The lamps use non-ionizing light and do not contain harmful UV radiation. Therefore, red light does not cause burns or DNA damage like UV light can. However, incorrect or prolonged use can cause mild side effects, such as temporary redness, a feeling of warmth, skin irritation, or sensitive eyes.
Always use the recommended distance, treatment duration, and frequency. At Liroma, we usually recommend short sessions of about 10 to 20 minutes, depending on the product, distance, and body area. Always use protective glasses for sensitive eyes or direct exposure to the face.

When you see results from red light therapy varies per person and per goal. Some users experience more relaxation, less stiffness, or a pleasant warm feeling in muscles and joints after just a few sessions. For visible skin improvement, support of collagen production, muscle recovery, or reduction of recurring complaints, more time is usually needed.
On average, many people use red light therapy 3 to 5 times per week for 4 to 12 weeks to notice a clear difference. For skin improvement, fine lines, recovery after exercise, or support for sore muscles and joints, consistent use is more important than one long session.
For the best results, we recommend incorporating red light therapy into your regular routine. Consider using it in the morning for energy, after sports for muscle recovery, or in the evening for relaxation.
Yes, red light therapy can be used daily in many cases, as long as you use the device according to the recommended guidelines. Daily use can be beneficial for goals such as skincare, muscle recovery, relaxation, supporting circulation, and reducing stiffness.
However, using it more often does not always mean faster results. Red light therapy works best with a good balance between light dosage, distance, and frequency. Sessions that are too long can actually be less effective or cause temporary skin irritation or skin fatigue.
A practical guideline is:
3 to 5 times per week for general use and buildup
Daily short use for experienced users or specific routines
10 to 15 minutes per session depending on the device and distance
Always listen to your body. If you experience sensitivity, warmth irritation, or discomfort, it’s better to skip a day or shorten the session.
The pulse function in red light therapy panels flashes the light on and off at a specific frequency.
Research has shown that this can lead to deeper penetration, better stimulation of cell activity, less heat generation, and more targeted therapy, depending on the chosen frequency. It offers additional options for a personalized treatment.
Yes, all panels from Liroma have a timer to set the correct treatment time.
There is little research on red light therapy during pregnancy. One study with 380 pregnant women showed that it was safe for both mother and fetus.
However, it is advised that pregnant women consult a doctor before starting light therapy.
In 1967, the Hungarian doctor Endre Mester accidentally discovered that laser light promoted hair growth and wound healing in rats. This laid the foundation for red light therapy, also known as photobiomodulation.
NASA experimented in the 1990s with red LED lamps to help plants grow better in space. They discovered that this light also aided wound healing and recovery. As a result, red light therapy was further researched for medical applications, such as preventing muscle breakdown and delayed healing during space flights.
Although red light therapy is becoming increasingly popular as a treatment for pain and skin improvement, additional research is needed to fully confirm all health claims.
