Red light therapy for fast wound healing

Check how red light therapy devices can help your wound healing

Wound Healing Using Red Light Therapy

Red light treatment or therapy (RLT) is a technique that uses low wavelength red light to treat skin conditions. The majority of dermatologists believe that it can be beneficial for various skin diseases, scars, and symptoms of aging, including age spots and wrinkles.

Increasing numbers of health practitioners are incorporating RLT into their practices due to the substantial in-depth investigations being conducted by scientists. Continue reading if this multi-purpose therapy procedure mentions have caught your attention and piqued your interest.


At home wound healing with red light therapy, how is RLT used?

Using low-wavelength red light to expose the body is a simple operation that may be completed in under an hour. Low-level laser light treatment is another moniker for the procedure, though RLT is likely to be more often used in practice. This red light is natural and can penetrate deep into the skin, where it can be absorbed and utilized by the cells.

According to a study published in the journal Seminars in Cutaneous Medicine and SurgeryTrusted Source, mitochondria found in skin cells can absorb light particles. As a result, increased production of adenosine triphosphate, which serves as the energy supply for all cells, can be facilitated by this method.

Many scientists believe that this function is responsible for the potential sound effects of RLT. The cells might respond more effectively to injury and regenerate themselves due to the extra energy.

Many studies have demonstrated that the treatment has potential, but more thorough clinical research in people will be required to establish the treatment’s potential clinical applications.

Having said that, there are some possible benefits of RLT, especially in healing wounds, which we shall discuss in greater detail in the sections that follow.

Effects of red light therapy on wound healing, speeding wound healing using red light therapy:

For almost 40 years, red light therapy has been utilized to enhance skin wound healing and other health benefits.Let’s discuss the effects of red light therapy on wound healing.

When it comes to wound healing, the red light treatment uses specific wavelengths of light to trigger good biological procedures in the human body. A 630 to 660nm-ranged red light and 810 to 850nm-ranged near-infrared light are the most therapeutic wavelengths, collectively referred to as “red light treatment.”

Using near-infrared light therapy to treat wounds is most effective when it reaches deeper into the body. With NIR and red light therapy, wounds in muscles, bone, and connective tissue can be effectively treated.

The first way of providing red light was using low-level laser light treatment devices. Wound healing using red LED light therapy has never been easier, thanks to recent light-emitting diode (LED) light technology developments.

The skin’s cells respond by creating more energy when exposed to red or near-infrared wavelengths of light. This helps the cells perform at their best. As a result, red light therapy significantly impacts wound healing.

The cellular effects of red light treatment are felt immediately. Various systems in the body are supported by the improved functioning of individual cells, which accelerates the healing process of the wound. Moreover, red light therapy can help after surgery, check out this article on the topic.

Increased Energy in the Cells:

For the first time, researchers from the Institute for LIT (Laser and Information Technologies) in Russia have found when NIR or red light reaches mitochondrial chromophores (the sections of molecules responsible for their color), they trigger a process known as photoactivation. Red light treatment, in particular, increases ATP synthesis in the mitochondria as a result of this interaction.

As stated earlier, stimulated cells can perform better, fight pathogens better, and repair and replenish themselves.

Wound Healing Using Red Light Therapy

A modulated inflammatory response reduces chronic inflammation:

 As soon as an acute inflammatory reaction, new skin structures are swiftly formed. Oxidative stress in cells can worsen the damage done to them by the inflammatory process if it continues past the acute stage.

Michael R. Hamblin, one of the world’s best experts on red light treatment, said in a 2017 publication that inflammation was significantly reduced in animal trials that dealt with wound healing, brain injury, spinal cord injury, and arthritis.

According to Dr. Hamblin, in human investigations on chronic non-healing wounds, these findings were particularly significant. For example, researchers that studied red light therapy on persons with diabetic ulcers discovered that it reduced inflammation but did not cause chronic inflammation, meaning that the body benefited from acute inflammation (an essential aspect of healing).


Red light therapy for fast wound healing, stem cell activation:

When the red light is shined on the bone marrow, it activates stem cells, which migrate to where the harm occurred. This stem cell deployment is critical because nearby cells communicate with each other. In addition, emerging cells can be influenced by damaged cells. However, the new cells receive the correct signals by replacing the damaged cells with healthy stem cells. This means that the new cells do not take on the traits of injured cells, but instead acquire the qualities needed.

Collagen production is normalized:

The deepest layers of a scar are stimulated by red light therapy, which promotes healthy collagen formation. Collagen can be organized into a regular lattice work to aid in the creation of healthy tissue and reduce scar formation.

Enhanced circulation of blood and lymphfFluid:

Lymph circulation and good blood are essential for effective recovery. This is because red light treatment improves microcirculation, which is blood flow through the smallest blood vessels. In addition, perfusion, the process through which blood or other fluid travels through blood arteries and into an organ or tissue, is also increased by this treatment.

Using Red Light Therapy to Heal Wounds at Home:

 Doctors should always treat wounds that require medical treatment. Even for minor wounds that don’t require medical attention, LED panels with high light energy output can be used to give red and NIR light therapy.

Go through the important points below to get the most out of low-level light treatment. Treatment should be applied many times a week, between 10 and 20 minutes, until the area has been cured. Keep the wound clean at all times.

  • Give your body what it needs by getting enough sleep, eating well, and reducing stress.
  • Use a LED panel for light therapy with a high light energy output for the best results. Portable, battery-operated gadgets aren’t strong enough to penetrate into the skin’s deeper layers and underlying tissue. They don’t have the power to execute the work at hand. 
  • Combine red and infrared light with an LED panel. Why? You’ll want to heal wounds from the surface down to their core.


When deciding on a red light therapy device, here are five things to keep in mind:

 The correct red light therapy gadget is required to get the most out of red light therapy. So what should you look for in red light therapy at home? Let’s see.



 Irradiance is the quantity of energy received by a given body part while utilizing a gadget. Consider it as the energy delivery rate. Higher irradiance for red light therapy at home can result in better benefits in less time.


 Typical red light treatment devices use frequencies from 650 nm (deep red penetrates the skin and affects mitochondria) to 850 nm (near-infrared, has more penetrative power to get into the tissue). This range is standard in many red light therapy devices.

Area of treatment:

Choose red light treatment equipment with maximal coverage if your budget allows, as larger devices release more light energy and function better. Larger devices also provide instant access to full-body red light therapy at home.

Product quality:

 Look for standards or certificates that authenticate the device’s legitimacy and safety to avoid buying a phony or harmful red light therapy gadget. Standards to look for include those relating to part safety and light calibration.


Finally, customer satisfaction and testimonials can show how the red light treatment gadget performs in specific cases. For example, some users comment on the device’s durability, ease of use, light intensity, and whether it requires any maintenance. Customers will also tell you if the company offers easy returns and replacements.


Ultimately, red light therapy is suitable for all skin types, even those most sensitive, and the science behind it is promising. Expect a non-invasive technique to treat specific skin issues, healing wounds while also slowing down the aging process.



Q. What color of LED light is most beneficial for wound healing?

Because red light treatment has an incredible capacity to heal, it is advisable to combine it with near-infrared and red light therapy to be the most effective.


Q. Is RLT suitable for healing wounds?

Red light therapy does have the ability to heal tiny open wounds, according to the research. The only exception to this rule is serious wounds that necessitate medical attention.
