Q. What is low-level laser therapy (3LT®)?

A. Low-level laser therapy is the use of low intensity photonic energy as a treatment modality.

Q. How does Low-Level Laser (3LT®) work?

A. Photonic stimuli excite the body’s cells infusing them with energy, with the three primary reactions being, reduction of inflammation, cell function and increased blood flow.

Q. What’s the difference between Lasers vs. LED?

A. Erchonia 3LT® devices used electric diodes, which are high end, culminated and strictly measured within a plus/minus .05%.  LEDs are inexpensive, non-focused wide range light sources.  The primary difference is in performance and depth of penetration.  Laser diodes penetrate, working subcutaneously, LEDs do not affecting the surface only.


Q. What clinical studies have been conducted using low-level laser?
