Epilation with a long-pulse 1064 nm Nd:YAG laser in facial hirsutism.

Background: Facial hirsutism and hypertrichosis are common problems and a methods are available to clinicians for the unwanted hair in a large number of patients. Several depilatory laser systems are now available and one of these modalities is the long-pulse Nd:YAG laser.

Objective: To evaluate the efficacy of the long-pulse Nd:YAG laser in removing unwanted facial hair.

Methods: In all, 29 patients completed their treatment course with a long-pulse (4 ms) Nd:YAG (1064 nm line) with fluences between 56 J/cm(2) and 70 J/cm(2). The average reduction in hair density was assessed using hair count on digital photographs at removal 3, 6 and 9 months postoperatively. The hair-free interval was variety of also evaluated.

Results: The average reduction of in the hair count (the same diameter as the baseline for the criterion) was 43% at 3 months, 36% at 6 months, and 46% at 9 months. The hair-free interval with laser was two- to sixfold longer than with self-applied methods. No significant complications were observed in the range of skin types treated, even in the darker skin types.

Conclusions: The long-pulse Nd:YAG laser is an effective and safe method for long lasting hair removal in all skin types. The delay in hair regrowth most likely explains patient satisfaction.
