Best Practices and Evidenced-Based Use of the 800 nm Diode Laser for the Treatment of Pseudofolliculitis Barbae in Skin of Color

摘要

The author's experience with the diode laser with hand piece (cooled convex sapphire lens) for hair removal has shown excellent results, especially with use in patients of color.The newer hair removal lasers have pulse durations that are much longer (100-400 ms) than traditional systems (20-40 ms), allowing darker skin types to be treated with little risk of complications given the appropriate settings. Longer pulse durations transmit laser energy at slower rates, allowing a maximum temperature rise of the hair follicle with minimum energy dispersion to the surrounding tissues. Under the right parameters, a planned treatment course, sun avoidance and protection, and pretreatment with a topical skin care regimen, results are extremely satisfying to patients.
