Red light therapy (RLT) is a treatment that uses low-level red and near-infrared light to penetrate the skin and stimulate cells. It’s also called photobiomodulation in more technical settings. This light penetrates the skin and is absorbed by mitochondria (the “energy producers” in your cells).It increases ATP (cellular energy), which supports: Repair processes Reduced inflammation Improved circulation RLT is used for a mix of cosmetic and recovery purposes: Skin & appearance Reducing fine lines and wrinkles Improving skin tone and texture Supporting collagen production Helping with acne (sometimes combined with blue light) Recovery & pain Muscle recovery after exercise Joint pain and stiffness Reducing inflammation Other uses (with varying evidence) Hair growth support Wound healing Mood/seasonal effects (less strong evidence vs light therapy for SAD)
