新型强脉冲光对面部皮肤美白作用的研究

目的：在对面部皮肤光老化、雀斑、痤疮、毛细血管扩张症等原发病治疗过程中，比较观察具有完美脉冲技术（optimal pulse technology，OPT）的新型强脉冲光（intense pulsed light，IPL）560～1200nm和590～1200nm两种波长对面部皮肤美白效果的作用。方法：将146例皮肤光老化、面部毛细血管扩张、雀斑和痤疮患者随机分为A组68例和B组78例，分别用IPL—OPT560～1200nm和590～1200nm波长治疗1～4次，治疗参数以原发病为目标进行设置，治疗间隔时间4周。以患者基础肤色变淡程度判定皮肤美白效果，肤色变淡程度分为无效、有效、显效3级。结果：A组显效率55．9％，总有效率83．8％：B组显效率61．5％，总有效率92．3％，后者优于前者，两组间总有效率比较无显著性差异。结论：新型IPL—OPT 560～1200nm和590～1200nm两种波长对面部皮肤均有较好的关白作用，疗效确切，差别无统计学意义。

Clinical study of whitening efficacy of facial skin with new type intense pulsed light (IPL-OPT)

Objective To compare the treatment effect of two spectrum of new types intense pulsed light （IPL-OPT） on the primary diseases such as skin photoaging,fleck,acne,telangiectasia. Methods 146 patients with skin photoaging, facial talangiectasia, fleck and macula were divided in two groups at random： 68 patients were treated by using spectrums ranging 560-1200nm and 78 patients were treated by using 590-1200nm of the new type intense pulsed light （IPL-POT）. Each patient was treated 1 to 4 times. The interval of the treatments was 4 weeks. Evaluated whitening effects on basic skin color of patients and the level of improvement were grade as invalid, utility and excellence. Results In new type IPL-OPT/560-1200nm group, the obvious efficiency was 55.9%,the whole efficiency was 83.8%. In 590- 1200nm group, the figure is 61.5% and 92.3% respectively. The whitening effect of latter was better. There has no statistically significant in total effective rate of two groups. Conclusion New type intense pulsed light （IPL-OPT） 560- 1200nm and 590-1200nm both have significant macroscopic whitening effect, which relate to times of treatment.The difference has no statistically significant.
