Red light therapy is a non-invasive treatment that uses low-level red and near-infrared light to support the body’s natural healing processes. It is commonly used to improve skin health, reduce the appearance of fine lines and wrinkles, and promote collagen production. Many people also use it to help relieve muscle soreness, joint discomfort, and inflammation. The therapy works by allowing light to penetrate the skin and interact with cells. This may help improve cellular energy production and tissue repair. Sessions are generally painless and do not involve ultraviolet (UV) radiation. Red light therapy is available in clinics, wellness centers, and some at-home devices. While research suggests benefits for certain conditions, results can vary depending on the individual and the condition being treated. It is often used alongside other treatments rather than as a replacement for medical care. Consulting a healthcare professional is recommended before using red light therapy for a medical condition.
