Lasers are considered the most efficient methods for hair reduction. The goal of these devices is to provide long-term effects without adverse reactions. This is a randomized split-body controlled study on body hair removal and pseudofolliculitis (PFC) treatment, comparing the standard single pass (SP) emission with the multipass emission (Moveo handpiece) with 755 alexandrite laser. Patients with Fitzpatrick skin types I to VI underwent laser hair removal, by treating one side of the body using the standard SP and the other side with Moveo. Treated areas included face, arms, legs, trunk, axillae and groins. Each patient underwent a minimum of three to a maximum of eight treatments, every 6 weeks, with a 6-month follow-up. Hair reduction, side effects, PFC severity score and patient satisfaction were recorded for all patients. Totally, 108 patients were enrolled, of whom 96 were female. The overall hair reduction rate (% ± SD), independent of skin type, was estimated as 87 ± 5.5 for standard SP and 78.5 ± 7.6 for Moveo. No significant statistically differences were found between the two groups. Side effects included pain, which was higher after standard SP (4.2 ± 0.8) than after Moveo treatment (1.5 ± 0.5). A statistical significant difference between the two devices was found (P = .0002). PFC score improved in almost all the patients. Patients declared to be satisfied with both the treatments, reporting a preference for Moveo (84% vs 16%) (P = .01). Standard SP and Moveo 755 alexandrite laser seems to be safe and effective treatments for hair removal in all Fitzpatrick skin types and for PFC. Moveo has a higher security profile with fewer side effects.
激光被认为是减少毛发最有效的方法。这些设备的目标是提供长期效果而无不良反应。这是一项关于身体脱毛和假性毛囊炎（PFC）治疗的随机分体对照研究，比较了标准单次发射（SP）与多遍发射（Moveo 手柄）755 翠绿宝石激光的效果。Fitzpatrick 皮肤 I-VI 型患者接受激光脱毛，一侧使用标准 SP 治疗，另一侧使用 Moveo 治疗。治疗区域包括面部、手臂、腿部、躯干、腋窝和腹股沟。每位患者至少接受 3 次最多 8 次治疗，每 6 周 1 次，随访 6 个月。记录所有患者的毛发减少、副作用、PFC 严重程度评分和患者满意度。共纳入 108 例患者，其中 96 例为女性。独立于皮肤类型，总体毛发减少率（%±SD）估计为标准 SP 为 87±5.5%，Moveo 为 78.5±7.6%。两组之间无统计学差异。副作用包括疼痛，标准 SP 后疼痛更高（4.2±0.8），Moveo 后疼痛较低（1.5±0.5）。两种设备之间存在统计学差异（P = 0.0002）。几乎所有患者的 PFC 评分都有所改善。患者对两种治疗均表示满意，报告更喜欢 Moveo（84%对 16%）（P = 0.01）。标准 SP 和 Moveo 755 翠绿宝石激光似乎是所有 Fitzpatrick 皮肤类型和 PFC 的安全有效脱毛治疗方法。Moveo 的副作用较少，安全性更高。
