Post-procedural ecchymosis can last up to two weeks and diminish patient satisfaction. Laser-assisted clearance is documented with pulsed-dye devices, but data on 1064-nm picosecond/nanosecond platforms remain sparse.
To evaluate a staged 1064-nm laser protocol for accelerating bruise resolution after dermal filler injections.
Three women (aged 40-52 years, Fitzpatrick III-IV) with facial bruises were treated on Day 2-3 using a picosecond 1064-nm Nd:YAG laser (0.20-0.30 J/cm², 8-10 mm spot, 8-10 Hz, 8-10 min). A nanosecond Q-switched 1064-nm Nd:YAG session followed on Day 4-7 (2.5-3.0 J, 8 mm spot, 30-40 stacked shots) with peri-session cooling. Clinical photographs and Global Aesthetic Improvement Scale (GAIS) ratings were obtained through Day 7.
All bruises faded substantially within 4-5 days; near-complete resolution was achieved by Day 6-7. GAIS scores were "Much" or "Very Much Improved" in every case. No pain, post-inflammatory hyperpigmentation, or other adverse effects occurred. Compared with typical spontaneous recovery (≈10-14 days), the protocol shortened visible downtime by 40%-60%.
A sequential 1064-nm picosecond-nanosecond regimen appears safe and effective for rapid ecchymosis clearance after aesthetic injections. Larger controlled studies are warranted to optimise fluence, cost-effectiveness, and applicability to other procedural bruises and darker skin types.
术后瘀斑可持续长达两周，会降低患者满意度。脉冲染料设备已记录了激光辅助清除瘀斑的情况，但关于1064纳米皮秒/纳秒平台的数据仍然稀少。
评估一种分阶段的1064纳米激光方案，以加速真皮填充剂注射后瘀斑的消退。
三名面部有瘀斑的女性（年龄40 - 52岁，菲茨帕特里克皮肤分型III - IV型）在第2 - 3天使用皮秒1064纳米钕:钇铝石榴石激光进行治疗（能量密度0.20 - 0.30 J/cm²，光斑8 - 10毫米，频率8 - 10赫兹，治疗8 - 10分钟）。在第4 - 7天进行纳秒调Q 1064纳米钕:钇铝石榴石激光治疗（能量2.5 - 3.0 J，光斑8毫米，30 - 40次堆叠脉冲），每次治疗期间进行冷却。在第7天前获取临床照片和全球美学改善量表（GAIS）评分。
所有瘀斑在4 - 5天内明显消退；在第6 - 7天实现了近乎完全消退。在每种情况下，GAIS评分均为“改善很多”或“改善非常多”。未出现疼痛、炎症后色素沉着或其他不良反应。与典型的自然恢复（约10 - 14天）相比，该方案将可见的恢复时间缩短了40% - 60%。
1064纳米皮秒 - 纳秒序贯治疗方案对于美容注射后快速清除瘀斑似乎是安全有效的。需要进行更大规模的对照研究，以优化能量密度、成本效益以及对其他手术瘀斑和更深肤色类型的适用性。
