Abstract

BACKGROUND:

Hirsutism is a common disorder in women of reproductive age, and androgen disturbances may aggravate the condition. Limited evidence exists regarding efficacy of hair removal in this specific population and no data are available for patients with verified normal testosterone levels.

OBJECTIVES:

To compare efficacy and safety of intense pulsed light (IPL) vs. long-pulsed diode laser (LPDL) in a well-defined group of hirsute women with normal testosterone levels.

METHODS:

Thirty-one hirsute women received six allocated split-face treatments with IPL (525-1200 nm; Palomar Starlux IPL system) and LPDL (810 nm; Asclepion MeDioStar XT diode laser). Testosterone levels were measured three times during the study period. Patients with intrinsically normal or medically normalized testosterone levels throughout the study were included in efficacy assessments (n = 23). Endpoints were reduction in hair counts assessed by blinded photoevaluations at baseline and 1, 3 and 6 months after final treatment, patient-evaluated reduction in hairiness, patient satisfaction, treatment-related pain and adverse effects.

RESULTS:

IPL and LPDL reduced hair counts significantly, with median reductions from baseline of 77%, 53% and 40% for IPL and 68%, 60% and 34% for LDPL at 1, 3 and 6 months, respectively. At 6 months follow-up, there was no significant difference between treatments in terms of hair reduction (P = 0·427), patient assessment of hairiness (P = 0·250) and patient satisfaction (P = 0·125). Pain scores were consistently higher for IPL [median 6, interquartile range (IQR) 4-7] than LPDL (median 3, IQR 2-5) (P < 0·001).

CONCLUSION:

Hirsute women with normal or medically normalized testosterone levels responded equally well to IPL and LPDL treatments of facial hairiness, but the efficacy declined over 6 months.
