Pain-Free, Hair-Free™ breaks the mold of previous laser hair removal systems. The system’s unique IN-Motion™ technology, along with the sweeping motion of the laser, safely and gently heats the targeted area under your skin while a patented DualChill™ mechanism ensures the surface of your skin stays cool and comfortable throughout your treatment. The sweeping motion also eliminates any skipped or missed spots common to other types of laser hair removal.
