RATIONALE

Dermatologists are using low level laser (author’s note, these are not “laser” devices) for therapeutic rather than for surgical procedures. At least one study has shown low level light applicaiton can liquefy stored fat.

STUDY SUMMARY

635 nm laser of 1.0 joule per centimeter, with a total energy delivered of 0.9 mW/cm2, does not release fat.

METHOD

Test porcine invivo (live pig) and cultured human preadipocytes (pre-fat cells).

Apply 635 nm (red) light at 1.0 joule per cm^2 (0.9 mW).

Control groups received no light treatment.

Apply light to human cells for 60 minutes.

In porcine group, pre-treat:

  • group 1: suction assisted, no radiation
  • group 2: ultrasound assisted, no radiation
  • group 3: 635 nm at 1.0 J/cm^2
  • group 3a: no exposure
  • group 3b: 15 minutes exposre
  • group 3c: 30 minutes exposure
  • group 3d: 60 minutes exposure

Perform histological and electron microscope scans.

RESULTS

There were no histological or cellular differences between controls and radiated specimens. 1 Joule/cm^2 635 nm light delivering 0.9 mW did not enhance lipoplasty results.

EMF CHANNEL COMMENTARY

Red light therapy is most therapeutic in the 100 mW/cm2 area.

At 0.9 mW/cm2, this study tested red light at 1/100th of that power.

The laser didn’t burn fat at this low energy level.
