Nonablative lasers treat photoaged skin and stimulate new collagen formation while sparing epidermal damage.
To evaluate the effectiveness and safety of nonablative fractional diode combination laser skin resurfacing treatment (1440 and 1927 nm) in mild-to-moderate photoaged skin.
The entire face was treated with both 1440-nm and 1927-nm wavelengths per treatment, with a total of 4 treatments spaced 1 month apart. Follow-up occurred at 1 and 3 months post-treatment. Outcomes were improvement in the appearance of ≥1 measure of photodamage (rhytides, skin texture, dyschromia/pigment, skin radiance, pore size, and overall appearance) at the 3-month (primary) and 1-month (secondary) follow-up visits. Safety was monitored throughout the study.
Participants ( N = 28; 89% female; mean age, 40 years) experienced significant mean improvement from baseline in all measures of photodamage with combination laser treatment at 1 and 3 months post-treatment (all p < .001). No serious adverse events occurred. Post-treatment erythema and edema were minimal, and pain levels remained consistent throughout treatment. Most participants (96.4%) considered their overall appearance as improved and expressed satisfaction with treatment outcomes.
Nonablative combination laser skin resurfacing treatment was well tolerated and significantly improved measures of photodamage in photoaged skin across diverse skin types.
非剥脱性激光可治疗光老化皮肤并刺激新的胶原蛋白形成,同时避免表皮损伤。
评估非剥脱性分数二极管联合激光皮肤磨削术(1440和1927纳米)治疗轻至中度光老化皮肤的有效性和安全性。
每次治疗均使用1440纳米和1927纳米波长对整个面部进行治疗,共进行4次治疗,每次间隔1个月。在治疗后1个月和3个月进行随访。观察指标为在3个月(主要)和1个月(次要)随访时,至少1项光损伤指标(皱纹、皮肤质地、色素沉着/色斑、皮肤光泽、毛孔大小和整体外观)有所改善。在整个研究过程中监测安全性。
参与者(N = 28;89%为女性;平均年龄40岁)在治疗后1个月和3个月时,联合激光治疗使所有光损伤指标较基线均有显著平均改善(所有p < .001)。未发生严重不良事件。治疗后红斑和水肿轻微,整个治疗过程中疼痛程度保持一致。大多数参与者(96.4%)认为其整体外观有所改善,并对治疗效果表示满意。
非剥脱性联合激光皮肤磨削术耐受性良好,可显著改善不同皮肤类型的光老化皮肤的光损伤指标。
