Fractionated mid-infrared resurfacing.

Fractional resurfacing devices thermally alter microscopic treatment columns in the skin, leaving intervening areas between the columns untouched. Because only a fraction of the skin is being modified, untreated areas are able to rapidly repopulate the treatment columns to greatly reduce recovery time and adverse events. Mid-infrared fractional systems have shown improvement in treating photoaging, scars, rhytides, dyschromia, and textural disorders. An additional advantage is that they are safe and effective for the treatment of nonfacial areas such as the neck, chest, and extremities.
