Photodamaged skin is characterized not only by rhytides, but also by epidermal and dermal atrophy, rough skin texture, irregular pigmentation, telangiectasias, laxity, and enlarged pores. There is growing interest in the development of noninvasive methods to treat photodamaged skin. Skin photorejuvenation is the visible improvement of photodamaged skin using a laser or other light source. A noncoherent, broadband, pulsed light source is effective in the treatment of vascular and pigmented lesions of the skin. This study evaluates the role of intense pulsed light in the rejuvenation of photo aged skin.
The purpose of this study was to evaluate and quantify the degree of visible improvement in photodamaged skin following a series of full-face, intense pulsed light treatments.
Forty-nine subjects with varying degrees of photo-damage were treated with a series of four or more full-face treatments at 3-week intervals using a nonablative, nonlaser intense pulsed visible light source. Fluences varied from 30 to 50 J/cm2. Subject evaluation and skin biopsies were used to assess treatment results.
All aspects of photodamage including wrinkling, skin coarseness, irregular pigmentation, pore size, and telangiectasias showed visible improvement in more than 90% of subjects with minimal downtime and no scarring. Eighty-eight percent of subjects were satisfied with the overall results of their treatments.
Treatment of photodamaged facial skin using a series of full-face treatments with intense pulsed light is a new and effective noninvasive method of skin rejuvenation with minimal risk and no patient downtime.
光损伤皮肤的特征不仅在于皱纹,还包括表皮和真皮萎缩、皮肤质地粗糙、色素沉着不规则、毛细血管扩张、皮肤松弛和毛孔粗大。人们对开发治疗光损伤皮肤的非侵入性方法的兴趣与日俱增。皮肤光 rejuvenation 是指使用激光或其他光源使光损伤皮肤得到明显改善。非相干、宽带、脉冲光源对治疗皮肤的血管性和色素性病变有效。本研究评估强脉冲光在光老化皮肤 rejuvenation 中的作用。
本研究的目的是评估和量化在一系列全脸强脉冲光治疗后光损伤皮肤明显改善的程度。
49 名不同程度光损伤的受试者接受了一系列四次或更多次全脸治疗,每隔 3 周使用非剥脱性、非激光强脉冲可见光源进行一次治疗。能量密度从 30 到 50 J/cm²不等。通过受试者评估和皮肤活检来评估治疗效果。
光损伤的各个方面,包括皱纹、皮肤粗糙、色素沉着不规则、毛孔大小和毛细血管扩张,在超过 90%的受试者中都有明显改善,停机时间最短且无疤痕。88%的受试者对治疗的总体效果感到满意。
使用一系列全脸强脉冲光治疗光损伤面部皮肤是一种新的、有效的非侵入性皮肤 rejuvenation 方法,风险最小且患者无需停机。
