What Is Red Light Therapy (Photobiomodulation)? Red light therapy (RLT) — more precisely called photobiomodulation (PBM) — uses specific wavelengths of red (≈600–700 nm) and near-infrared light (≈700–900 nm) to trigger non-thermal biological responses in cells by stimulating mitochondrial activity and cellular signaling. This can increase cellular energy (ATP), modulate inflammation, and support tissue repair.This therapy has gained attention for its ability to promote healing, reduce inflammation and alleviate pain in various conditions. Scientific literature suggests there are nearly 60 other names for RLT, such as: low level light therapy (LLLT) soft laser therapy cold laser therapy biostimulation photonic stimulation low power laser therapy (LPLT) In 2025–26, major medical groups and research reviews have continued to refine clinical recommendations for PBM, including the first European clinical guide for supportive cancer care .

Red light therapy (RLT), also known as low-level light therapy (LLLT) or photobiomodulation, is a non-invasive treatment that uses specific wavelengths of red and near-infrared light to stimulate cellular function. This therapy has gained attention for its ability to promote healing, reduce inflammation and alleviate pain in various conditions. Scientific literature suggests there are nearly 60 other names  for RLT, such as: low level light therapy (LLLT) soft laser therapy cold laser therapy biostimulation photonic stimulation low power laser therapy (LPLT) The benefits of red-light therapy extend to several areas of health. For neuropathy, it helps reduce pain and improve nerve function by increasing blood flow and reducing inflammation. In cases of myopathy, red light therapy shows promise in enhancing muscle recovery and reducing muscle fatigue. Additionally, research suggests it may have positive effects on skin health, myopia, cognitive function and more. Low-Level Red-Light ...
