Light therapy is rapidly becoming a core technology in both professional aesthetic treatments and home skincare routines. From skin repair and inflammation relief to eye-area comfort and overall rejuvenation, LED light therapy offers a non-invasive, science-backed approach to long-term skin health.
Whether you are a beauty professional, lash artist, or a home user seeking safer, effective skincare solutions, this guide explains how light therapy works, who it’s for, and how to use it correctly — with expert insights, real-world use cases, and practical recommendations.
Light therapy uses specific wavelengths of LED light to stimulate biological responses in skin cells. These wavelengths penetrate the skin at different depths and influence cellular activity, including collagen production, circulation, and inflammation regulation.
According to medical and dermatological sources such as Healthline and Cleveland Clinic, red and near-infrared light therapy have been clinically studied for their ability to support skin healing, improve skin texture, and reduce signs of aging.
