LED light therapy (also called photobiomodulation or low-level light therapy) is a non-invasive treatment that uses specific wavelengths of light-emitting diodes to stimulate cellular activity in the skin. Different colours penetrate to varying depths: blue light targets the surface, while red and near-infrared light reach deeper layers. The light is absorbed by cells, boosting energy production (ATP), reducing inflammation, and triggering beneficial biological responses without heat or UV damage.
Medical sources support LED therapy for a range of skin concerns when used consistently:
Professional in-clinic devices generally deliver higher energy than at-home units, and results typically build with a series of regular treatments. LED therapy is suitable for most skin types and is often used alone or combined with other aesthetic procedures such as microneedling or PRP.
