[摘要]目的：本研究旨在采用半張臉（Split-face）模式自身對照觀察點(diǎn)陣CO2激光結(jié)合強(qiáng)脈沖光治療中國人群的光老化皮膚臨床效果與安全性。方法：選擇2019年3月-2019年12月筆者醫(yī)院整形美容科門診就診的28例Fitzpatricks Ⅲ和Ⅳ型皮膚的中國女性就醫(yī)者為研究對象。采用隨機(jī)數(shù)字表法選取一側(cè)面頰部給予單獨(dú)治療（強(qiáng)脈沖光治療3次），另一側(cè)給予聯(lián)合治療（強(qiáng)脈沖光治療2次，點(diǎn)陣CO2激光治療1次）。在治療前和治療后30d評估患者的皮膚狀況，包括含水量、經(jīng)表皮失水率、彈性、斑點(diǎn)、紫外線光斑、紅色區(qū)域、棕色斑、皺紋、膚質(zhì)、毛孔孔徑，以及不良反應(yīng)。結(jié)果：與單獨(dú)強(qiáng)脈沖光治療相比較，點(diǎn)陣CO2激光聯(lián)合強(qiáng)脈沖光可顯著增加皮膚彈性、減小毛孔孔徑、改善皺紋和膚質(zhì)（分別為P=0.004、P=0.039、P=0.015及P=0.035）。兩種治療方法在改善光老化引起的色素沉著方面效果相似。聯(lián)合治療不損害表皮的屏障功能，治療后無感染、色素減退或瘢痕形成。點(diǎn)陣CO2激光治療后1個月發(fā)生炎癥后色素沉著，在所有療程結(jié)束后30d消失。結(jié)論：點(diǎn)陣CO2激光結(jié)合強(qiáng)脈沖光治療中國人群的光老化皮膚優(yōu)于單用強(qiáng)脈沖光，安全性好。

Abstract： Objective The purpose of this study is to observe the clinical effect and safety of carbon dioxide dot-matrix laser combined with intense pulsed light on the photoaging skin of the Chinese population by using a split-face mode. Methods? This study included 28 Chinese female patients with Fitzpatricks Ⅲ and Ⅳ skin who visited theThe Department of Aesthetic Plastic Surgery of our hospital from March to December 2019. The patient's random one side of the cheek was treated with single treatment （3 times of intense pulsed light treatment）， and the other side was treated with combined treatment （2 times of intense pulsed light treatment and 1 time of carbon dioxide dot laser treatment）. The patient's skin condition was evaluated before treatment and 30 days after treatment， including water content， transepidermal water loss， elasticity， spots， ultraviolet spots， red areas， brown spots， wrinkles， skin texture， pore size， and adverse reactions. Results? Compared with intense pulsed light treatment alone， CO2 dot-matrix laser combined with intense pulsed light can significantly increase skin elasticity， reduce pore size， and improve wrinkles and skin texture （P=0.004， 0.039， 0.015， and 0.035， respectively）. The two treatments have similar effects in improving pigmentation caused by photoaging. The combined treatment does not damage the barrier function of the epidermis， and there is no infection， hypopigmentation， or scarring after treatment. Post-inflammatory pigmentation occurred 1 month after CO2 laser treatment and disappeared 30 days after treatment. Conclusion? CO2 dot-matrix laser combined with intense pulsed light is better than the strong pulsed light alone in treating Chinese people's photoaging skin， and it is safe.
