Use of a variable long-pulse alexandrite laser in the treatment of facial telangiectasia.

Background: The alexandrite laser selectively targets melanin and hemoglobin. We used the alexandrite laser with variable pulse widths to treat facial telangiectasia.

Methods: Nineteen patients were enrolled in this study, which consisted of two parts: a series of test spots over a range of pulse durations (3-80 ms) and treatment over a larger area based on the pulse width-specific outcomes from the test spots.

Low-fluence 1,064-nm laser hair reduction for pseudofolliculitis barbae in skin types IV, V, and VI.

Purpose: To evaluate the efficacy of a 1,064-nm neodymium-doped yttrium aluminium garnet (Nd:YAG) laser using lower than traditional fluences (22-40 J/cm(2)) for treatment of pseudofolliculitis barbae (PFB).

Methods: Twenty-two patients with PFB refractory to conservative therapy received five weekly treatments over the anterior neck using a 1,064-nm Nd:YAG laser at 12 J/cm(2). Pulse duration was 20 ms with 10 mm spot size.
