Does Red Light Therapy Actually Work?

One such treatment that has been gaining significant attention is red light therapy. Many people are curious and often ask, “Does red light therapy actually work?” To answer this question, let’s delve into what red light therapy is, how it works, and what the science says about its effectiveness.

What is Red Light Therapy?

Red light therapy (RLT), also known as low-level laser therapy (LLLT) or photobiomodulation, involves exposing the skin to low levels of red or near-infrared light. Unlike ultraviolet (UV) light, which can damage skin cells, red and near-infrared light is thought to stimulate cellular function and repair.

How Does Red Light Therapy Work?

Red light therapy works by penetrating the skin to a depth of about 5 millimeters, where it can be absorbed by the cells. This light energy is then converted into cellular energy, enhancing the cells’ function and promoting healing. The process involves several mechanisms:

  1. Increased ATP Production: The mitochondria, known as the powerhouse of the cell, absorb the light and produce more adenosine triphosphate (ATP), the energy currency of the cell. Increased ATP production enhances cellular repair and regeneration.
  2. Reduced Inflammation: Red light therapy has anti-inflammatory effects, which can help reduce pain and swelling in injured or damaged tissues.
  3. Collagen Production: It stimulates collagen production, which can improve skin texture and elasticity, reducing the appearance of wrinkles and scars.
  4. Enhanced Circulation: RLT improves blood flow to the treated areas, promoting better oxygen and nutrient delivery to tissues.

Benefits of Red Light Therapy

  1. Skin Health: RLT is widely used for improving skin conditions, such as acne, scars, and wrinkles. It can also help reduce the appearance of stretch marks and promote faster wound healing.
  2. Pain Relief: Many people use red light therapy for pain management. It can be effective for conditions like arthritis, tendonitis, and muscle injuries.
  3. Hair Growth: Some studies suggest that RLT can stimulate hair growth in individuals with alopecia or thinning hair.
  4. Improved Mood and Sleep: Exposure to red light can influence circadian rhythms, potentially improving sleep quality and mood.

Scientific Evidence

Numerous studies have investigated the effectiveness of red light therapy, with promising results. For instance:

  • Skin Health: A study published in the journal Photomedicine and Laser Surgery found that red light therapy significantly improved skin complexion and increased collagen density.
  • Pain Relief: Research published in The Lancet demonstrated that RLT reduced pain and disability in patients with chronic joint disorders.
  • Hair Growth: A clinical trial published in Lasers in Surgery and Medicine reported that red light therapy significantly increased hair density in participants with androgenetic alopecia.


Red light therapy is a promising treatment with a range of potential benefits, from improving skin health to reducing pain and promoting hair growth.
