Red Light Therapy at Well Room

What Is Red Light Therapy?

Red light therapy (also called photobiomodulation or low-level light therapy) uses specific wavelengths of red and near-infrared light to penetrate the skin and stimulate cellular processes. The light is absorbed by mitochondria (the energy-producing structures in cells), which may increase cellular energy production (ATP), support tissue repair, and reduce inflammation.

Red light therapy uses visible red light (typically 620–700nm wavelength) and near-infrared light (700–1100nm). Red light penetrates closer to the skin's surface and is primarily studied for skin health. Near-infrared penetrates deeper into tissue and is studied for pain, inflammation, and muscle recovery.

What the Research Says

Red light therapy has a growing body of research, though most studies are small:

Skin health: Multiple studies show red light therapy can stimulate collagen production, improve skin texture, and reduce signs of aging. A 2014 study in Photomedicine and Laser Surgery found significant improvements in skin complexion and collagen density.

Wound healing: Red and near-infrared light have been shown to accelerate wound healing in several clinical studies. This is one of the better-supported applications.

Pain and inflammation: Some evidence supports red light therapy for reducing joint pain and inflammation, particularly in conditions like osteoarthritis.

What's not well-supported: Claims about significant weight loss, detoxification, or cancer treatment from red light therapy are not supported by evidence.
