Fraxel Laser Only Treats 20 Percent of the Skin with Multiple Passes?

gengen
During a Fraxel Restore treatment, when the technician does multiple passes over the same area, how does the laser know which area is the same skin being treated and not untreated skin?I'm trying to wrap my head around how the laser only treats 20% of the skin at a time when it does multiple passes.
