Explore how red light therapy enhances sleep quality and skin health by boosting melatonin production and stimulating collagen—clinically supported and easy to use.
Red Light Therapy (RLT), also called photobiomodulation or low-level laser therapy, is a non-invasive treatment that delivers red to near-infrared light (about 660–850 nm) to the skin. The light energy may stimulate cellular repair and regeneration, and some devices are cleared by the U.S. Food and Drug Administration for specific indications.
Red light therapy is thought to act through photobiomodulation, a process in which mitochondria absorb light photons and may increase adenosine triphosphate (ATP) production, potentially supporting cell repair and reducing oxidative stress.
