What Is Red Light Therapy?
Red light therapy (RLT) is a treatment that may aid in the healing of your skin, muscle tissue, and other body parts. It exposes you to low-intensity red or near-infrared light.
Infrared light is a sort of energy that your eyes cannot perceive but that your body can detect as heat. Red light is comparable to infrared light, except it can be seen.
Low-level laser treatment (LLLT), low-power laser therapy (LPLT), and photobiomodulation (PBM) are all terms for red light therapy.
How Does Red Light Therapy Work?
Red light therapy involves exposing your skin to a red light-emitting bulb, device, or laser.
A component of your cells known as mitochondria, sometimes known as the “power generators” of your cells, absorbs and converts it into energy. According to some experts, this helps cells mend themselves and grow healthier. For example, this promotes skin and muscular tissue repair.
Red light treatment emits deficient levels of heat and does not cause pain or burns to the skin. It is not the same type of light used in tanning salons, and it does not expose your skin to harmful UV rays.

As a study in the Journal Seminars in Cutaneous Medicine and Surgery [1], mitochondria in the skin cells can absorb these light particles.
This can help the cells produce more adenosine triphosphate, the energy source for all cells.
Many experts attribute Red Light Therapy’s potential positive effects to this function. With this extra energy, the cells may be able to respond to harm and repair themselves more effectively.
Although there has been preliminary research into Red Light Therapy, there is no conclusive evidence that it is a valuable treatment. However, much research indicates that the treatment has promise, but more extensive clinical trials in people will be needed to establish Red Light Therapy’s potential applications.
There are some possible benefits of Red Light Therapy, which we shall discuss in the sections below.
- Improving skin health
- Improving acne
- Wound healing
- Weight Loss
- Reducing pain
- Enhancing bone recovery
- Anti-inflammatory benefits

How Is Red Light Therapy Used?
Since the first experiments in space, hundreds of medical examinations and thousands of laboratory studies have been undertaken to establish whether Red Light Therapy has medical benefits.

Many experiments have yielded encouraging results, yet the benefits of red light treatment remain debatable. For example, the Centers for Medicare and Medicaid Services (CMS) has found insufficient data to indicate that these devices are superior to conventional therapies for wounds, ulcers, and pain.
More clinical research is required to demonstrate the efficacy of Red Light Therapy. At the moment, however, there is some evidence that Red Light Therapy may have the following advantages:
- help with wound healing [2] and tissue repair
- increase hair growth [3] in men suffering with androgenic alopecia
- aid in the treatment of carpal tunnel syndrome
- promotes the healing of slow-healing wounds such as diabetic foot ulcers
- decreases psoriasis lesions
- helps in the alleviation of short-term pain and morning stiffness in persons with rheumatoid arthritis
- decreases some of the negative side effects of cancer treatment, including oral mucositis [4]
- improves skin complexion and builds collagen [5] to diminish wrinkles
- helps to mend sun damage [6]
- reduces the recurrence of cold sores caused by herpes simplex virus infections
- improves the health of joints [7] in people with degenerative osteoarthritis of the knee
- helps diminish scars
- relieves [8] in people with pain in the Achilles tendons
Due to insufficient concrete evidence, insurance providers do not currently endorse or cover Red Light Therapy for certain illnesses. However, some insurance companies are now covering the use of Red Light Therapy to prevent oral mucositis during cancer therapy.

5 Factors To Consider
- Irradiance – Irradiance is the amount of energy a specific part of your body receives over a period of time. Some red light therapy devices have a high mW/cm2 reading on the surface of the device and not on the object exposed to it. The most used format to measure irradiance is milliwatts per square centimeter.
- Frequency – The range of frequency used in typical red light therapy devices is from 650 nm (a deep red, penetrates the skin and acts on mitochondria) to 850 nm (near-infrared, penetrates deeper into tissue). Generally speaking, red light wavelengths penetrate the skin and promote collagen production and wound healing. On the other hand, near-infrared light can go deeper, enabling it to target deeper wounds and joint or muscle pain. These lower frequencies can also treat skin issues such as acne and oil regulation.
- Treatment coverage area – Some red light therapy devices are portable and can be used at home or abroad. Some larger devices emit more light energy and better performance than smaller units. Larger devices also allow users to get direct access to a full-body red light treatment at a moment’s notice.
- Quality of the product – Be on the lookout for standards or certificates that attest to the device’s authenticity and safety. To prevent buying a fake or unsafe red light therapy device, always check the safety of the parts used and how well-calibrated it is about the user’s body.
- Customer feedback – Red light therapy device reviews can offer a small window into how the device in question works in real life. Some customers leave details regarding results, ease of use, actual light intensity, and whether the device is prone to damage or requires some investment in maintenance.

Conclusion
Red light therapy is a novel technology that uses laser light to transport photons deep into the body to promote specific health benefits.
The system can help you grow your hair, improve your skin, erase acne, wrinkles, and lines, heal wounds, relieve joint and muscle pain, rebuild strength, raise your mood, and even treat neurodegenerative disorders.
Red light therapy has shown encouraging results in treating various skin problems, but there isn’t much agreement among scientists on the treatment’s benefits.
