Non-ablative fractional lasers (NAFL) generate microscopic non-contiguous columns of thermal injury in the dermis, resulting in collagen remodeling. This manuscript details our experience with a novel 1,565 nm scanned, erbium-doped fiber NAFL for the treatment of facial photodamage.
STUDY DESIGN/MATERIALS AND METHODS: A prospective, open-label clinical trial was conducted at two clinical sites in the United States on 16 female subjects with a mean age of 49.6 years, Fitzpatrick skin types II to IV, and a baseline Fitzpatrick-Goldman Wrinkle and Elastosis Score (FGWES) of 3-6. Each subject received three treatments at 4-5 week intervals with follow-up assessments at 1, 3, and 6 months after the last treatment.
The mean FGWES demonstrated a statistically significant decrease from baseline both at 3 months (-0.58 ± 0.23, P = 0.02) and 6 months (-0.66 ± 0.22, P = 0.008) after the last treatment. Fifty percent (95%CI [24.21%, 68.49%]) of subjects showed a significant (at least 1 grade) improvement in FGWES from baseline at 3-month follow-up. At least 72% of subjects perceived the results as "moderate" to "very good" at 3 months post-treatment, with comparable satisfaction rates. Treatments were not associated with a high level of pain or discomfort and typical downtime was less than 2 days. No unexpected adverse events or serious adverse events were reported.
The 1,565 nm erbium-doped scanned NAFL is an effective treatment for facial wrinkles with a favorable recovery and side effect profile.
非剥脱性分次激光(NAFL)在真皮层产生微小的、不连续的热损伤柱,从而导致胶原蛋白重塑。本文详细介绍了我们使用一种新型的1565纳米扫描掺铒光纤NAFL治疗面部光损伤的经验。
研究设计/材料与方法:在美国的两个临床地点对16名女性受试者进行了一项前瞻性、开放标签的临床试验。受试者平均年龄49.6岁,皮肤类型为菲茨帕特里克II至IV型,基线菲茨帕特里克-戈德曼皱纹和弹性评分(FGWES)为3 - 6分。每位受试者每隔4 - 5周接受三次治疗,并在最后一次治疗后的1、3和6个月进行随访评估。
末次治疗后3个月(-0.58±0.23,P = 0.02)和6个月(-0.66±0.22,P = 0.008)时,平均FGWES较基线有统计学意义的下降。50%(95%CI[24.21%,68.49%])的受试者在3个月随访时FGWES较基线有显著(至少1级)改善。治疗后3个月时,至少72%的受试者认为效果为“中等”至“非常好”,满意度相当。治疗未伴有高水平的疼痛或不适,典型的停工期少于2天。未报告意外不良事件或严重不良事件。
1565纳米掺铒扫描NAFL是治疗面部皱纹的有效方法,恢复良好且副作用小。
