The ProFractional mode of the Sciton Joule allows for "fractional" resurfacing of the skin, in which only a fraction of the skin surface is treated at each session. With the ProFractional mode, the computer-generated pattern of the laser creates thousands of microscopic channels in the skin. The physician can customize the depth of these channels to the needs and features of the patient's skin and to the amount of downtime that is practical for the patient.

The untreated skin adjacent to the treated area allows for much more rapid healing than in conventional laser resurfacing, in which 100 percent of the skin surface is ablated. As the skin heals, new collagen is deposited resulting in better skin quality.

ProFractional laser treatments are usually performed as a series of several treatments with each session separated by several weeks’ time.
