Understanding Red Light Therapy
Red light therapy uses specific wavelengths of light to penetrate the skin and stimulate various biological processes. This can improve skin health, reduce inflammation, and promote healing.
What Is Red Light Therapy?
Red light therapy is a treatment that uses low-level wavelengths of red light to treat skin issues, pain, and other conditions. Unlike ultraviolet (UV) light, it does not damage the skin. Instead, it is absorbed by the mitochondrion, the cell's powerhouse, to produce energy. It is often used in dermatology and for pain relief, and it has applications in both medical and cosmetic fields.
How Does Red Light Therapy Work?
Red light therapy works by emitting low-level wavelengths of red or near-infrared light. These wavelengths penetrate the skin and are absorbed by the mitochondrion.
