Treatment of facial freckles by StarLuxG in comparison with Q-switched double Nd：YAG laser

摘要:

目的：StarLuxG强脉冲光与Q-开关倍频Nd：YAG激光治疗雀斑的疗效对比研究。方法：50例雀斑患者，随机分为2组，每组25例，StarLuxG组采用StarLuxG强脉冲光，激光组采用Q-开关倍频Nd：YAG激光（波长532 nm），根据患者皮损深浅选择适当的参数。针对2组间治疗雀斑的总有效率和不良反应采用卡方检验进行比较，P＜0.05，差异有统计学意义。结果：StarLuxG组总有效率 88%；激光组总有效率 92%，差异无统计学意义（ ?字2=2.569，P ＞0.05）；StarLuxG组0例（0%）患者出现暂时性色素沉着；激光组6例（24%）患者出现暂时性色素沉着，差异有统计学意义（ ?字2=6.818，P＜0.05）。随访6~12个月，术后无感染及瘢痕发生。结论：StarLuxG强脉冲光是一种有效、安全、无创便捷的治疗面部雀斑的方法，无停工期，不影响患者的正常生活及工作。

Abstract:

Objective：To compare the therapeutic effect of StarLuxG and Q-switched double Nd：YAG laser in freckle treatment. Methods：Totally 50 patients with freckles were divided into two groups randomly with 25 patients in each group. They were treated with StarLuxG or Q-switched double Nd：YAG laser with a proper parameter according to the depth of skin pigment. The total effective rate and adverse reaction（temporary pigment）of the two groups were compared by chi-square test. There were statistically significant differences when the P value＜0.05. Results：The total effective rates of group StarLuxG and group Laser were 88% and 92% respec－tively，without significant differences between the two groups（ ?字2=2.569，P ＞0.05）. The adverse effect rates（temporary pigment）of group StarLuxG and group laser were respectively 0% and 24%，with statistical differences between the two groups（ ?字2=6.818，P＜0.05）. No infection and scarring was noted during the 6-12 months follow-up. Conclusion：StarLuxG is an effective，safe and noninvasive way to treat freckle，which doesn’t affect patient’s life or work and doesn’t require any downtime.
