What is red light laser therapy?

Red light laser therapy is an innovative treatment gaining immense popularity thanks to its ability to safely and effectively improve a wide range of health concerns. But what exactly is this groundbreaking therapy, and how does it deliver such transformative results?

Red Light Laser Therapy

Red light laser therapy has become the hot new treatment on the wellness scene, but most people still don’t understand what it is or how it can transform your health. This guide will walk you through the proven science behind red light lasers and show you how to tap into their amazing benefits.

Red Light Laser Therapy History

The origins of red light therapy trace back to the 1960s when scientists discovered that low-level lasers could improve wound healing. Researchers began experimenting with light to stimulate cell growth and treat tumors.

In the decades since, thousands of studies have documented powerful therapeutic effects of red and near-infrared light for varied uses – everything from reducing joint pain to stimulating hair growth.

Red light laser devices were initially rather large, expensive machines used in clinical settings. But thanks to technological advances, today red light therapy is widely accessible with compact, affordable at-home devices.

From NASA research on red light for astronaut muscle atrophy to elite sports teams integrating it for performance, photobiomodulation therapy continues gaining momentum and credibility.

What is Red Light Laser Therapy?

Red light laser therapy, also known as low-level laser therapy (LLLT) or photobiomodulation, is a non-invasive treatment that uses low-powered lasers or light-emitting diodes (LEDs) to stimulate cellular metabolism and promote tissue repair. This therapy has been used for several decades in various medical fields, including sports medicine, dermatology, and pain management. Sessions take just minutes, are completely safe for daily use, and carry no side effects.

How Red Light Laser Therapy Works?

The lasers used in red light laser therapy emit specific wavelengths of red and near-infrared light. These light waves penetrate the skin and are absorbed by the mitochondria in the cells. The mitochondria then use this energy to produce ATP, which is the molecule that provides energy to the body’s cells.[1]

The increased production of ATP helps to promote cellular metabolism, which in turn promotes tissue repair and reduces inflammation. This therapy also helps to increase blood flow to the treated area, which can help to reduce pain and swelling.

Red Light Laser Therapy Effects

1. Pain relief – Red light laser therapy has been shown to reduce pain and inflammation in the body. This therapy is particularly effective for treating chronic pain conditions like arthritis and fibromyalgia.

2. Improved skin health – Red light laser therapy is commonly used to treat skin conditions like acne, rosacea, and psoriasis. This therapy helps to reduce inflammation, promote collagen production, and improve skin tone and texture.

3. Faster healing – Red light laser therapy promotes tissue repair and helps to speed up the healing process. This therapy is commonly used to treat sports injuries and post-surgical wounds.

4. Improved circulation – Red light laser therapy helps to increase blood flow to the treated area, which can improve circulation and reduce swelling.

Conditions that Can Be Treated with Red Light Laser Therapy

Red light laser therapy has been shown to be effective in treating a variety of conditions, including:

* Skin conditions, such as acne, eczema, and psoriasis
* Hair loss
* Scarring
* Arthritis
* Fibromyalgia
* Migraines
* Tinnitus
* Sleep disorders
* Depression
* Anxiety

Does Red Light Laser Therapy Really Work?

Over 5,000 research studies and clinical trials have demonstrated the effectiveness of red light laser therapy for an incredible array of health concerns. Here are just some of the most profound ways the science supports its benefits:

– Collagen production is significantly increased, thereby reducing wrinkles and scar tissue. In a 2009 study, more than 90% of users saw an improvement in skin smoothness and tone after red light laser therapy.[2]

– Reduces inflammation and pain associated with diseases such as arthritis and neuropathy. Clinical trials have shown a 70% reduction in the pain of arthritis symptoms after red light laser therapy. Patients also noticed a significant reduction in morning stiffness and increased palm dexterity.[3]

– Accelerates wound healing after surgery or injury. A 2015 study on traumatic wound healing in rats showed that the use of a red laser improved wound healing in rats.[4]

– Promotes hair regrowth by stimulating hair follicles and increasing blood flow to the scalp. Participants who used the red laser therapy saw a 51 percent increase in hair density over 17 weeks.[5]

With thousands of studies validating its safety and efficacy across diverse applications, red light laser therapy remains one of the most researched modern modalities.

What are The Risks of Red Light Laser Therapy?

While red light laser therapy is generally safe and non-invasive, there are some risks associated with the treatment. These risks include:

Eye damage: Red light laser therapy can cause eye damage if the lasers are directed at the eyes.

Interference with other treatments: Red light laser therapy can interfere with other treatments, such as chemotherapy or radiation therapy.

Red light laser therapy is generally considered safe and well-tolerated. However, there are certain groups of people who should avoid this therapy or use it with caution.

  • People with epilepsy
  • People who are pregnant or breastfeeding
  • People taking photosensitizing medications
  • people with photosensitive conditions, such as lupus or porphyria

It is always best to consult with a healthcare professional before beginning any new therapy, including red light laser therapy, to determine if it is safe and appropriate for your individual needs and medical history.


Overall, red light laser therapy is a safe and effective treatment option for a wide range of medical conditions. If you’re considering this therapy, be sure to talk to your healthcare provider to determine if it’s right for you.
