In fractional laser skin resurfacing, a device called a fractional laser delivers precise microbeams of laser light into the lower layers of skin, creating deep, narrow columns of tissue coagulation. Coagulated tissue in the treatment area stimulates a natural healing process that results in fast growth of healthy new tissue.
The procedure can be used on the face, neck, chest, arms and hands. Discomfort during treatment typically is minimal. The approach produces long-lasting results with virtually no downtime. A series of treatments over a one- to four-week interval may be required to achieve the desired results.
