What is red light therapy?

Red light therapy (RLT ) is a controversial therapeutic technique that uses red low-level wavelengths of light to treat skin issues, such as wrinkles, scars, and persistent wounds, among other conditions.

In the early 1990s, Red light therapy was used by scientists to help grow plants in space. The scientists found that the intense light from red light-emitting diodes (LEDs) helped promote the growth and photosynthesis of plant cells.

The red light was then studied for its potential application in medicine, more specifically to find out if Red light therapy could increase energy inside human cells. The researchers hoped that Red light therapy could be an effective way to treat muscle atrophy, slow wound healing, and bone density issues caused by weight lessness during space travel.

When Red light therapy  is used with photosensitizing medications, it’s referred to as photodynamic therapy. In this type of therapy, the light only serves as an activating agent for the medication.

There are many different types of red light therapy. Red light beds found at salons are said to help reduce cosmetic skin issues, like stretch marks and wrinkles. Red light therapy used in an medical office setting may be used to treat more serious conditions, like psoriasis, slow-healing wounds, and even the side effects of chemotherapy.

Ps: Infrared is an electromagnetic wave with a frequency between microwave and visible light. Red light is the use of visible light 600-700nm (accounting for more than 90%), infrared light 700-4000nm (accounting for less than 10%) comprehensive light wave for external irradiation, so that it produces important biological effects.

How does red light therapy work?

Red light is thought to work by producing a biochemical effect in cells that strengthens the mitochondria. The mitochondria are the powerhouse of the cell — it’s where the cell’s energy is created. The energy-carrying molecule found in the cells of all living things is called ATP (adenosine triphosphate).

By increasing the function of the mitochondria using Red light therapy , a cell can make more ATP. With more energy, cells can function more efficiently, rejuvenate themselves, and repair damage.

Red light therapy  is different from laser or intense pulsed light (IPL) therapies because it doesn’t cause damage to the skin surface. Laser and pulsed light therapies work by causing controlled damage to the outer layer of the skin, which then induces tissue repair. Red light therapy  bypasses this harsh step by directly stimulating regeneration of the skin. The light emitted by Red light therapy  penetrates roughly 5 millimeters below the skin’s surface.

How does red light therapy work

The principle of infrared physiotherapy is mainly the thermal effect (that is, heat).

When infrared ray irradiates our body, due to its strong penetrating ability, it can reach the gap between molecules or atoms, accelerate the vibration of molecules and atoms, and increase the distance, resulting in an increase in thermal motion energy.

Infrared rays continue to irradiate the skin, which will cause the temperature of the irradiated parts to rise, which is the thermal effect of infrared rays.

The thermal effect is actually well understood. Essentially, the body absorbs the energy of infrared rays and manifests itself in the form of local heat.

Red Light Therapy Panel For Human Body

We often see people saying that infrared physiotherapy can improve blood circulation, accelerate cell metabolism, reduce inflammation and relieve pain… Some also say that it can treat high blood pressure, diabetes, and even cancer.

Infrared panels are a great option to enjoy these benefits at home, used on your body parts.

The penetration of infrared rays is stronger than that of visible light, and it can penetrate the skin to increase the temperature of deep tissues, cause blood vessels to dilate, accelerate blood flow, and improve microcirculation, all of which are beneficial to the human body.

Of course, the heat energy generated by infrared rays can also change the permeability, colloidal state, bioelectricity, pH, and enzyme system of cells, thereby accelerating cell metabolism and functional recovery.

When it comes to the role of infrared physiotherapy, we can’t listen to other people’s praise. The more common clinical applications are anti-inflammatory and analgesic, such as the treatment of some osteoarthritis.

Some clinical studies have pointed out that infrared irradiation of the knee joint produces heat energy, which can improve local blood circulation, strengthen tissue nutrient metabolism, and accelerate the absorption of local exudates, thereby promoting the subsidence of swelling.

At the same time, the heat effect can also reduce the skeletal muscle tension around the knee joint, relieve muscle spasm, and reduce the excitability of sensory nerves, interfere with the pain valve, and help relieve pain.

The red light devices use red 660nm and Infrared 850nm leds which is chosen to give the ideal wavelengths found in the scientific research of the last three decades.

660nm of red light:

This light can be seen by the eyes and targets skin cells.

850nm of near infrared light:

This light cannot be seen by the eyes and targets deep tissue.

Improving skin health

Most people show interest in Red light therapy as a possible way to improve skin health.

The potential for using Red light therapy as a way to rejuvenate the skin has led to a large number of studies. As the review in the journal Seminars in Cutaneous Medicine and SurgeryTrusted Source notes, Red light therapy  may help rejuvenate the skin by:

  • increasing collagenproduction in the skin, which gives the skin its elasticity
  • increasing fibroblast production, which helps produce collagen and other tissue fibers
  • increasing circulation between blood and tissue cells
  • protecting cells from damage
  • increasing mRNA in the cells, which helps stimulate the cell
  • improving facial texture
  • reducing fine lines
  • reducing wrinkle severity
  • A clinical trial in the journal Photomedicine and Laser SurgeryTrusted Sourceexplored light treatment for some basic skin issues in a small group of 136 people. The researchers found that these light therapies could:
  • rejuvenate the skin
  • improve the complexion
  • improve the feeling of the skin

It is important to remember that many of the results regarding Red light therapy  come from animal or test tube studies, which explore the function of Red light therapy . Many of the human studies used very small sample sizes, as is evident in the clinical trial above.

These results show the potential for the therapy but are not conclusive evidence that it will work in every case.

Improving acne

Share on Pinterest Red light therapy might be an effective treatment for acne vulgaris.

As the review in Seminars in Cutaneous Medicine and SurgeryTrusted Source also notes, forms of light therapy are potential alternatives for the treatment of acne vulgaris.

Sunlight can alter the way the sebaceous glands behave. The sebaceous glands produce sebum, which may clog the pores and cause acne. Sunlight may help calm overactive glands.

The issue that many people have with sunlight exposure is that it comes with exposure to ultraviolet (UV) A and UVB rays, which may cause other skin issues over time. These can be severe and may include developing skin cancer.

Red light therapy, either alone or in combination with other treatments such as blue light therapy, is a potentially effective treatment for acne vulgaris. The light appears to penetrate deep into the skin and affect sebum production while also reducing inflammation and irritation in the area.

Wound healing

Red light may also be helpful in speeding up wound healing.

Research in the journal Anais Brasileiros de DermatologiaTrusted Source highlights the fact that light therapy may help wound healing in a few ways, such as by:

  • reducing inflammation in the cells
  • stimulating new blood vessels to form, which doctors call angiogenesis
  • increasing helpful fibroblasts in the skin
  • increasing collagen production in the skin

More studies on humans can help confirm these results.

Hair growth

A small study in the Journal of Cosmetic and Laser Therapy explored the effect of low-level light on people with alopecia.

The study revealed that people who received Red light therapy had improved hair density, compared with those in a control group.

The authors note that the effect was beneficial when people applied light in wavelengths of both 660 nanometres (nm) and 850 nm.

However, this was a smaller study, and more extensive clinical studies will help give backing to these claims.

Reducing pain

Red light therapy may also be an effective treatment for pain in people with certain conditions.

A review in the European Journal of Physical and Rehabilitation Medicine compiled the results of many studies surrounding Red light therapy and musculoskeletal disorders.

The research indicated that Red light therapy could effectively reduce pain in adults with different musculoskeletal disorders. The researchers note that practitioners who stick to the specific dosage recommendations seem to increase the effectiveness of the therapy.

Enhancing bone recovery

A review in the Journal of Photochemistry and Photobiology Trusted Source examines the potential for Red light therapy in treating facial bone defects.

The researchers’ results indicate that Red light therapy may help accelerate healing after treatment for facial bone defects. The review also notes that the therapy helped reduce inflammation and pain during the process.

However, the researchers did call for a more standardized approach to determine whether or not the therapy is effective.

Anti-inflammatory benefits

As research in the journal AIMS BiophysicsTrusted Source notes, many of the conditions that Red light therapy treats have their roots in inflammation.

Although the exact reason is not yet clear, Red light therapy has significant anti-inflammatory effects in the body. These effects are both local, where practitioners apply the light, and systemic, in other tissues and organs in the body.

The researchers explain that the helpful anti-inflammatory effects of Red light therapy, and the potential uses for this therapy, are abundant.
