In the 2000s, there was a significant expansion in technology that was described as “nonablative.” These devices featured several different wavelengths and technologies. What they shared in common was the goal of delivering improvement in skin appearance while minimizing downtime and complications. Most of the “less-invasive” devices relied on the advent of fractional technology. This was the design feat of having multiple very small laser pulses delivered in a gridlike fashion and allowed for a mosaic of treated and untreated skin. With islands of healthy skin next to treated skin, the healing process was thought to be more rapid.
