Photorejuvenation involves the use of lasers or light sources to reverse signs of photoaging. Multiple devices have been shown to be effective over the short-term.
To investigate the long-term clinical results on the face, neck and chest at 4 years using filtered flashlamp intense pulsed light (IPL) for treatment of photoaging changes of telangiectasias, dyspigmentation, and rough skin texture.
A chart review of 80 randomly selected patients with skin types I-IV who were treated by IPL during 1996 and 1997 was performed. Photos and patient self-assessment were graded for features of textural smoothness, telangiectasia severity, and blotchy pigmentation into four categories of worse, no change, slightly better (less than 50% improvement) and much better (greater than 50% improvement).
At 4 years following initial treatment, skin textural improvement was noted in 83% of the subjects. Telangiectasias were improved in 82% of subjects, while pigmentation remained improved in 79%. The median number of treatments was 3. The face responded slightly better than the chest or neck. Most common side-effects included temporary mild crusting (19%), erythema (15%) and purpura (6%).
Signs of photoaging including telangiectasias and mottled pigmentation of the face, neck, and chest, can be improved by IPL with a long-lasting result. Minimal or no downtime with minimal adverse effects can be achieved with the settings reported. Skin textural smoothing, although not easily quantified, is an additional benefit observed long-term.
光嫩肤是指使用激光或光源来逆转光老化迹象。多种设备已被证明在短期内有效。
使用过滤闪光灯强脉冲光(IPL)治疗面部、颈部和胸部的毛细血管扩张、色素沉着和皮肤质地粗糙等光老化变化,研究4年时的长期临床效果。
对1996年至1997年间接受IPL治疗的80例随机选择的I-IV型皮肤患者进行病历回顾。根据质地光滑度、毛细血管扩张严重程度和斑点状色素沉着等特征,将照片和患者自我评估分为四类:更差、无变化、略有改善(改善小于50%)和明显改善(改善大于50%)。
初始治疗后4年,83%的受试者皮肤质地得到改善。82%的受试者毛细血管扩张得到改善,79%的受试者色素沉着仍有改善。治疗的中位数为3次。面部的反应略优于胸部或颈部。最常见的副作用包括暂时性轻度结痂(19%)、红斑(15%)和紫癜(6%)。
IPL可改善面部、颈部和胸部的光老化迹象,包括毛细血管扩张和斑驳色素沉着,效果持久。按照报告的设置可实现最少或无停机时间,且副作用最小。皮肤质地的平滑,虽然不易量化,但也是长期观察到的额外益处。
