Red light therapy remains an investigational approach to tinnitus. Clinical trials report mixed results, and evidence does not establish lasting relief or a standard home protocol. The article examines proposed mechanisms, device limitations, safety, and regulatory claims, while outlining established care options such as CBT and hearing aids.

Low-level laser therapy (LLLT) uses red and near-infrared light to stimulate cellular repair by boosting mitochondrial ATP production without heat or drugs. Supported by strong evidence for musculoskeletal pain, wound healing, and hair regrowth, LLLT offers clinics a non-invasive, low-risk treatment option when proper dosimetry parameters are followed.
