Abstract

BACKGROUND

Traditional full-face resurfacing has been limited to erbium-doped yttrium aluminium garnet (Er:YAG) and carbon dioxide (CO2) lasers. These devices offer wavelength-specific advantages and disadvantages.

METHODS

Nine patients were enrolled in a pilot study of a resurfacing system using a 2790-nm erbium:yttrium-scandium-gallium-garnet (Er:YSGG) laser system. Two treatments were carried out 1 month apart over the entire face. Test spots were performed prior to the full-face sessions to determine the optimal fluence for 1-pass laser resurfacing. Biopsies were performed at the time of treatment and at the final follow-up visit one month after the second treatment. Clinical endpoints included changes in pigment dyschromias, wrinkles, and skin tone. All outcomes were graded by blinded observers.

RESULTS

Eight patients completed the 2 treatments. Biopsies showed thermal damage extending as deep as 80 microm below the stratum corneum. Reepithelialization was complete within 4 days. No scarring, post inflammatory hyperpigmentation (PIH), or infections were observed.

CONCLUSION

A 2790-nm laser can be used for skin rejuvenation with a 4 day recovery window.

摘要

背景

传统的全脸皮肤磨削术仅限于掺铒钇铝石榴石（Er:YAG）激光和二氧化碳（CO2）激光。这些设备具有特定波长的优缺点。

方法

9名患者参与了一项使用2790纳米掺铒钇钪镓石榴石（Er:YSGG）激光系统的皮肤磨削系统的初步研究。在整个面部进行了两次间隔1个月的治疗。在全脸治疗前进行测试光斑，以确定单次激光皮肤磨削的最佳能量密度。在治疗时和第二次治疗后1个月的最终随访时进行活检。临床终点包括色素沉着异常、皱纹和肤色的变化。所有结果均由不知情的观察者进行分级。
