This document summarizes the potential benefits of low-level laser therapy (LLLT) for anti-aging and healing applications. It discusses how LLLT may work by increasing ATP production and reducing oxidative stress at the mitochondrial level. It also reviews evidence that LLLT can reduce inflammation, promote wound healing, and help with conditions like arthritis, brain injuries, and hair regrowth through photobiomodulation effects on cell signaling and gene expression. The document examines key parameters for effective LLLT dosing and provides examples of clinical studies supporting its use.
