LLLT – Low Level Light Therapy is an incredible, safe, drug-free treatment to help your pets heal faster and treat and control pain! This treatment modality is often termed as Low Level Laser Therapy and Cold Laser Therapy. It’s not actually cold, it generates a small amount of heat (it’s not a therapeutic delivery of heat). So Cold Laser is a bit of misnomer. We stick with LLLT or should really use the term PBM for Photobiomodulation.
