BACKGROUND AND OBJECTIVES: There are a variety of different laser
hair removal systems currently available. There are also systems
with identical emitted wavelengths; yet their emitted pulse durations
vary. There are few data comparing these systems in an objective
manner.
STUDY DESIGN/MATERIALS AND METHODS: Fourteen subjects received
three treatments with two different pulse duration 755-nm alexandrite
lasers. Paired anatomic sites were treated three times with both
a 2-msec and a 10-msec system. Subjects were evaluated prior to
laser treatment and 6 months after the three treatments with manual
hair counts and incidence of complications.
RESULTS: The average percentage of hair reduction was 33.1% for
the 2-msec-pulse duration and 33.9% for the 10-msec-pulse duration
alexandrite laser. No cutaneous pigmentary changes or scarring
was noted 6 months after the final treatment.
CONCLUSION: The alexandrite laser is effective in removing unwanted
hair. There was no difference in response between a 2-msec and
a 10-msec alexandrite laser.
