The laser paddle (sold separately) contains 3 light frequencies. Each of those 3  light frequencies are also available in a probe, which attaches to the paddle for going deeper into the body and spot treating. It uses sign waves to induce the body to relax, dissolve, neutralize.

dental areas / under the jaw or on a specific tooth/gum into the stomach
deeper into the quads & hamstrings (tracing the muscles) along the spine/joints/vertebrae

The Violet light Clears emotion fast. Balances aura. Wrinkles, scars, DMT, (The Spirit Molecule), DNA , Stem Cells and Reverses Telomeres.
pointing up the nose helps pineal gland. Use in same places as the others, just clears emotions held in those tissues, which can be the blockage at a muscle healing.
The violet light is also very $$$$$ so most companies do not use them. They do a very specific thing: they hold way more information than red or infrared
