What is Red Light Therapy?

Red light therapy is a non-invasive treatment that employs low-level wavelengths of red light to promote healing and reduce inflammation. It works by penetrating the skin, stimulating cellular function, and increasing energy production in mitochondria, which helps in the repair and regeneration of tissues. RLT is commonly used in skin care, physical therapy, and sports medicine.

Different types of light, including red and near-infrared, are utilized in RLT devices, each targeting different skin depths and conditions. The treatment is often sought for its ability to accelerate wound healing, diminish scars, and improve skin tone.
