ProFractional Therapy

ProFractional Therapy

Overview

ProFractional is Sciton´s solution for achieving excellent resurfacing results with minimal downtime. Unlike full field resurfacing which removes the entire surface area of a treatment site, ProFractional ablates narrow-diameter channels into the skin, covering a fraction of the total treatment area. This action initiates the body´s wound healing response which stimulates fibroblasts to produce new collagen and elastin, while leaving the surrounding tissue intact for rapid healing. The benefits of ProFractional include increased patient comfort, shorter healing times, and tunable results that can range from subtle to dramatic.

ProFractional utilizes a 250 µm spot size and offers a range of treatment densities from 1.5% to 30% coverage. ProFractional-XC utilizes a 430 µm spot size and predefined treatment densities for greater speed. ProFractional-XC also provides the ability to add depth-selectable tissue coagulation for enhanced collagen remodeling.

Clinical Applications

ProFractional creates clean, micro-ablated channels in the skin, which activate fibroblast production and rejuvenate the collagen matrix. The result is the formation of new collagen and elastin, which combine to bring increased turgor and thickness to the skin. Leaving surrounding tissue intact helps promote rapid healing due to presence of stem cells and melanocytes in the papillary dermis.

ProFractional therapy can be used on all skin types, both on face and body.

Science + Technology

Better ablation through more efficient water absorption

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.

Science

Tunable Resurfacing Laser (TRL) technology

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.
