800 nanometer diode laser hair removal in African American patients: a clinical and histologic study
1Georgetown University Medical School, Center for Laser Surgery, Washington DC, USA.
Background:
Although numerous lasers are available for laser assisted hair removal, their use in individuals with a dark skin type presents many challenges due to competition from epidermal melanin.
Objective:
Our aim was to evaluate two 800 nm diode lasers (Lightsheer) with 30 msec and 100 msec pulse durations in the treatment of African American patients with skin types V and VI. Histologic studies, efficacy and side effects were examined in an effort to optimize laser hair removal procedures in this patient population.
Methods:
Facial, neck and axillary areas were treated using 800 nm diode lasers at 30 and 100 msec pulse durations with fluences between 15 J/cm2 and 40 J/cm2.
Results:
Both lasers could be used safely in skin type V and VI African American patients. Longer pulse durations enabled the delivery of higher fluences with minor and acceptable postoperative complication profiles.
Conclusion:
The Lightsheer diode laser (Coherent Medical, Santa Clara, CA, USA) operating at 30 msec and 100 msec can be safely used in hair removal procedures in African American patients.
