Red light therapy is a non-invasive wellness and skincare treatment that uses specific wavelengths of red and near-infrared light to help support skin health, muscle recovery, circulation, and overall cellular function. It is commonly used to help reduce the appearance of fine lines, wrinkles, acne, inflammation, joint discomfort, and muscle soreness by stimulating collagen production and cellular energy. Modern red light therapy devices come in forms such as LED masks, handheld wands, panels, and therapy belts for both facial and full-body use. Consistent use is often recommended for noticeable results, and many at-home devices are designed to provide convenient daily treatments with minimal discomfort or downtime.
