The technology
How a fractional CO2 laser resurfaces skin
A CO2 laser emits at 10,600 nm, a wavelength that water absorbs almost completely. Because skin is mostly water, the beam vaporizes tissue precisely where it lands and heats a thin zone around it, which tightens collagen and triggers new collagen as the skin heals. That is ablative resurfacing, and it remains the most effective single treatment for deep wrinkles, acne scars, surgical scars, sun damage and rough texture.
Fractional vs full ablative
A traditional CO2 laser treats the whole surface, which gives dramatic results with two or more weeks of recovery. A fractional CO2 laser passes the beam through a scanner that splits it into a grid of microbeams, treating a fraction of the surface (typically 5 to 30 percent per pass) and leaving untreated skin between the columns. The untreated tissue speeds healing, so downtime drops to 3 to 7 days with results that build over a course of one to three sessions. The FC100 is a fractional system; the FC300 can run fractional, full ablative or a hybrid of both in the same session.
What it treats
Fine lines and deep wrinkles, acne and surgical scars, stretch marks, enlarged pores, uneven tone and photoaging, skin laxity on the face, neck and hands, and (on the FC300 with its vaginal probe) gynecological rejuvenation protocols. The surgical cutter on the FC300 also performs excisions, lesion removal and other minor procedures.
