The Comet is the first and only permanent hair reduction technology to combine laser energy with radio frequency (RF) to provide the safest, comfortable solution for effective, predictable and fast hair removal treatments. By combining the light and electrical energy, it is possible to isolate the treatment area and leave the surrounding skin safer from potentially harmful side effects.
Here is how the Comet works — First, the diode laser is fired, which preheats the targeted hair follicles. A few milliseconds later, the bi-polar radiofrequency energy is fired. Like any electrical energy, radiofrequency follows the path of least resistance. Since the laser has just preheated the hair follicles, the radiofrequency follows that path and increases the level of heat in the precise area where it is needed to accomplish its objective. The picture below shows a visual depiction of the process.
The best thing about using both light and electrical energies in this synergistic manner is that it allows for better results with lower overall energy output — assuring the highest level of safety and comfort. In fact, the combination of light and radiofrequency energy requires only 60% of the light energy to be used to achieve the same effect as other lasers. Other laser systems using only one energy source can’t compare.
The Comet also stands apart from other diode hair removal systems in its safety because of Active Dermal Monitoring. This monitoring provides the clinician with feedback on the heat in the skin after each pulse. If the skin is becoming too warm, the clinician is able to instantly react and turn the energy down. If the skin isn’t warm enough, the clinician knows they can safely turn up the energy and achieve a more effective treatment.
In past years, the Lumenis LightSheer has been considered the best diode hair removal device.  However, the Comet has surpassed the LightSheer in a number of ways and we are confident that the Comet is now the best diode laser hair removal technology available. The following chart shows a direct comparison of the two machines.
