Facial hypertrichosis presents an enormous psychological burden for women.
Temporary hair removal (waxing, plucking, etc.) and electrolysis are prolon
ged and unsatisfactory methods of treatment. For a few years several laser
systems with varying wavelengths, pulse durations and energy fluences have
been used successfully in laser epilation, In the retrospective study on ha
nd, we report on results of 30 female patients with hypertrichosis in the f
acial area treated with the long pulse alexandrite laser at 20 msec (Cynosu
re PhotoGenica LPIR/Apogee; 755 nm; 20 msec; up to 30 J/cm(2); 10 or 12.5 m
m beam diameter) over an 18 month treatment period. After an average of 8 t
reatments, an average clearance rate of 75% could be achieved. Fair hair (w
hite/blond/red) only showed a clearance rate of 10%, Hypo- and hyperpigment
ation did not appear. The most frequent adverse effects were the occasional
appearance of scattered crusting (17%), which healed without consequences,
and folliculitis (13%). The average post-treatment observation time lasted
3.25 months. The long-pulsed alexandrite laser at a pulse duration of 20 m
sec is an effective and safe method of treatment of hypertrichosis in the f
acial region of women. Black hair responds considerably better to the laser
treatment than fair hair. A longer post-treatment observation time is nece
ssary, though, in order to provide evidence for the permanence of the succe
ss of the method.
