  • Treatment sites included: axillae, bikini, extremities, face, and trunk
  • Spot sizes of 10–15 mm, fluences ranging from 20-50 J/cm2, 3 msec pulse-width, and a dynamic cryogen spray skin cooling system.

Study Results:

  • Mean hair reduction of 74% for all areas
  • Significant correlation between efficacy and fluence (higher fluence = higher efficacy)
  • Transient side effects only. No scarring or lasting adverse events.
