ProFractional Therapy provides excellent resurfacing results with minimal downtime. ProFractional Therapy ablates narrow channels into the skin, covering a fraction of the total treatment area.
ProFractional therapy provides independent control over the depth of ablation and coagulation. The physician can precisely tune the laser to the exact tissue effect desired – from pure ablation to pure coagulation, and every combination in between.
ProFractional utilizes an erbium:YAG laser, which was chosen due to its high ablation efficiency. Erbium has a much higher absorption in the target chromophore water than CO2 (see graph below) which gives erbium the ability to vaporize tissue with very little thermal conduction. By contrast, due to their comparatively low absorption by water, CO2 lasers have lower ablation efficiency and therefore, unavoidably, conduct a significant amount of heat into the tissue.
Erbium’s high water absorption is only part of the story. What truly sets ProFractional apart is TRL technology, which gives the user the ability to adjust the depth of ablation and coagulation independently. By modulating the laser’s energy to deliver supra-ablative pulses, ProFractional is able to vaporize any depth of tissue from 25 to 1500 µm per pass with extreme precision. If coagulation is desired, ProFractional-XC delivers a train of sub-ablative laser pulses that heat the tissue to a selectable depth without vaporizing it.
ProFractional’s TRL technology can ablate from 25 µm to 1500 µm with exacting precision.
