Low-Fluence 1,064-nm Laser Hair Reduction for Pseudofolliculitis Barbae in Skin Types IV, V, and VI

PURPOSETo 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) for treatment of pseudofolliculitis barbae (PFB). METHODSTwenty-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. Pulse duration was 20 ms with 10 mm spot size. Topical anesthesia was not used. Treatments were completed 15 minutes after patient arrival. Patients presented for 2- and 4-week follow-up. Ten evaluators used a Global Assessment Scale (GAS) to assess dyspigmentation, papule counts, and cobblestoning by comparing baseline to 4-week follow-up visit photographs. Hair and papule counts were performed on five patients and compared with the GAS. Investigators recorded adverse effects using a visual analog and side effects scale. RESULTSEleven patients demonstrated 83% improvement on the GAS (p
