Red light therapy, also known as low-level light therapy (LLLT), is a non-invasive treatment that uses red and near-infrared light to stimulate cellular activity and promote healing in the body. This therapy involves exposing the body to specific wavelengths of red and near-infrared light, typically through a specialized device that emits the light.

Red light therapy is believed to work by penetrating the skin and stimulating the mitochondria in cells to produce more energy, which can help to repair and regenerate damaged cells and tissues. This therapy has been shown to have potential benefits for a variety of conditions, including skin conditions, such as acne and psoriasis, as well as pain, inflammation, and muscle recovery.

Red light therapy may be administered in a clinical setting by a healthcare professional, or it may be performed at home using a specialized device. The treatment is generally considered safe, with few side effects reported. However, it is important to consult with a healthcare professional before starting any new therapy.
