Introduction
Light has profound and diverse effects on the human body, influencing sleep-wake cycles, circadian rhythmicity, mood, and immune function. In recent decades, scientists have begun exploiting the body's responses to light with photobiomodulation, a non-invasive, light-based therapeutic technique. Photobiomodulation employs specific wavelengths of light (measured in nanometers, nm) to stimulate biological processes within cells and tissues, triggering a cascade of physiological responses. A growing body of evidence suggests that photobiomodulation has potential applications in medicine, dentistry, cosmetic procedures, and scientific research. This article presents the history and current clinical evidence of photobiomodulation and describes the mechanisms and modalities that drive its effects.
In brief, research demonstrates that photobiomodulation may:
- Enhance collagen production and reduce the appearance of fine lines on the skin.
- Reduce pain...
