Red light therapy, also known as photobiomodulation or low-level laser therapy (LLLT) , is an innovative treatment that uses specific wavelengths of light, usually in the red or near-infrared spectrum, and aims to promote several health benefits.
Red light therapy uses LED panels that emit both red light and NIR (near-infrared) light. This light penetrates deep into your skin and cells, where it stimulates the mitochondria, the 'power plants' of your cells.
This process promotes the production of ATP (adenosine triphosphate) , a substance that provides your body with energy. Compare it to how plants use sunlight for photosynthesis. Only in this case, your cells use the light energy for repair and renewal.
Red light and near-infrared light (NIR) have the unique property of penetrating deep into your skin, sometimes up to 10 millimeters deep. As a result, the light reaches not only the superficial skin layers, but also deeper tissues such as muscles and joints. This makes red light therapy suitable for both skin care and treating deeper complaints.
Once the light passes through your skin, it is absorbed by the mitochondria – the ‘powerhouses’ of your cells. Mitochondria contain a special enzyme called cytochrome c oxidase that can absorb light.
This process helps the mitochondria to more effectively produce energy in the form of adenosine triphosphate (ATP) .
The increase in ATP means your cells have more energy available to perform their functions optimally. This results in faster regeneration of damaged tissue, improved cell function and more effective recovery. This process is essential for many health benefits, such as pain reduction, recovery after exercise and improving your skin texture.
In 1967, Hungarian physician 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 with red LED lights in the 1990s to help plants grow better in space. They found that this light also helped with wound healing and recovery. This led to further research into red light for medical applications, such as preventing muscle breakdown and delayed healing during spaceflight.
Although RLT is becoming increasingly popular as a treatment for pain and skin improvement, additional research is needed to fully confirm all health claims.

Wavelengths refer to the distance between successive peaks of a light wave, measured in nanometers (nm) .
In red light therapy these range from visible red light (approximately 620-700 nm) to near infrared light (700-1000 nm). Each wavelength penetrates to a different depth in the body and has specific effects on tissues and cells.
This wavelength targets superficial skin problems. It stimulates the production of collagen and elastin, making your skin firmer and reducing fine lines.
In addition, 630nm has anti-inflammatory properties that help treat acne. It kills acne-causing bacteria and reduces redness and irritation. Ideal for smooth, healthy skin!
The 660nm wavelength is perhaps the most popular in the world of light therapy. It penetrates deeper than 630nm and is extremely effective for wound healing, improving skin texture and reducing inflammation.
In addition, it promotes microcirculation, which results in healthier, more radiant skin. This versatile wavelength is often used for both skin and tissue repair.
For those who want to treat deeper muscles and joints, 830 nm is the perfect choice. This light penetrates deep into the body and is effective in relieving pain, healing injuries and stimulating blood flow in muscles.
It is especially popular among people with chronic pain and athletes who want to recover faster after intensive training.
The 850nm wavelength goes even further and reaches the deepest layers of the body, such as bones and tendons. This makes it popular among athletes and people recovering from serious injuries.
It stimulates the production of ATP, the energy source of your cells, which is essential for repair and tissue regeneration. This makes 850nm a powerful tool for deep repair and support of the whole body.
RLT is known to be a safe and effective treatment . It uses non-ionizing red light that penetrates deep into the skin to stimulate cell repair and collagen production. Unlike UV light, it is not harmful and does not cause burning or DNA damage. However, if used incorrectly, some mild side effects may occur, such as
To avoid possible side effects, it is essential to use the equipment according to the instructions.

Simply put, red light is visible to the naked eye and penetrates several millimeters deep into your skin. Infrared light, on the other hand, is not visible and reaches deeper layers of the body, even into muscles and joints. Both forms work together to support a wide range of biological processes.

Scientific literature shows that RLT is known by several names, including:
There is little research on red light therapy during pregnancy. One study with 380 pregnant women showed that it was safe for mother and fetus. However, it is advised that pregnant women consult a doctor before starting light therapy.
In general, red light therapy is safe, but always follow the instructions for use. At high light intensities and too long use, redness of the skin and other complaints can occur.
Do not use light panels if you are taking medications that make your skin or eyes more sensitive. Talk to your doctor if you have had skin cancer or have an eye disease before starting red light therapy.
We recommend irradiating one body part per day. Multiple body parts in one day is therefore possible.
The pulse function on red light therapy panels flashes the light on and off at a specific frequency. Research has shown that this can provide deeper penetration, better stimulation of cell activity, less heat generation and more targeted therapy, depending on the frequency chosen. It offers additional options for a personalized treatment.
