调Q激光与强脉冲光治疗面部雀斑的疗效比较

Comparison of Efficacy of Q-switched Laser and Intense Pulsed Light on Facial Freckles

目的:探究调Q激光与强脉冲光治疗面部雀斑的疗效及对皮损情况和不良反应的影响。方法:选取2021年1月-2022年9月就诊于笔者医院的130例面部雀斑患者,按就诊顺序随机分为对照组和观察组,每组65例。对照组采用强脉冲光治疗,观察组采用调Q激光治疗。比较两组治疗前后皮肤生理特征、美学效果及疗程、皮损情况、不良反应、患者美观满意度。结果:两组患者治疗期间不良反应总发生率比较差异无统计学意义(P>0.05),停止治疗3~6个月后均自行恢复。治疗前,两组患者斑点,纹理,皱纹,毛孔评分,皮损面积、颜色评分比较差异无统计学意义(P>0.05)。治疗1次后,两组皮肤生理状况及皮损状况均得到明显改善,且观察组上述评分均低于对照组(P<0.05);观察组美容治疗总有效率高于对照组(P<0.05)。观察组治疗时间及次数少于对照组(P<0.05)。两组患者美观满意度比较差异无统计学意义(P>0.05)。随访6个月后,所有患者无复发。随访1年后,两组复发率比较差异无统计学意义(P>0.05)。结论:与强脉冲光相比,调Q激光改善皮肤生理特征效果更好,治疗面部雀斑疗效更确切。调Q激光与强脉冲光治疗雀斑的近期疗效良好,但远期复发率较高。强脉冲光治疗雀斑的皮损情况少于调Q激光治疗。两者不良反应均较少,美观满意度相当。

Objective To evaluate the cosmetic efficacy of Q-switched laser and intense pulsed light(IPL)in the treatment of facial freckles and to assess their impact on skin lesion status and adverse reactions.Methods A total of 130 patients with facial freckles treated at the hospital between January 2021 and September 2022 were included in this study.Patients were randomly assigned to either the control group or the observation group,with 65 patients in each.The control group received IPL treatment,while the observation group underwent Q-switched laser treatment.Comparisons were made between the two groups before and after treatment regarding skin physiological characteristics,cosmetic outcomes,treatment duration,skin lesion status,adverse reactions,and aesthetic satisfaction.Results During treatment,there was no statistically significant difference in the overall incidence of adverse reactions between the two groups(P>0.05).All adverse reactions resolved spontaneously within 3 to 6 months post-treatment.Before treatment,there were no significant differences in the scores for spots,texture,wrinkles,pores,lesion area,and color between the groups(P>0.05).After one treatment session,significant improvements in skin physiological status and lesion scores were observed in both groups,with the observation group showing greater improvements(P<0.05).The total effective rate of cosmetic treatment was higher in the observation group(P<0.05).Additionally,the treatment time and frequency were shorter or lower in the observation group compared to the control group(P<0.05).Aesthetic satisfaction did not differ significantly between the two groups(P>0.05).After six months of follow-up,no recurrences were reported in either group.After one year,the recurrence rates were similar between the two groups(P>0.05).Conclusion Compared to IPL,Q-switched laser treatment is more effective in enhancing skin physiological characteristics and provides superior efficacy for treating facial freckles.Both Q-switched laser and IPL demonstrate good short-term efficacy,but both are associated with a high long-term recurrence rate.IPL treatment is associated with fewer skin lesions compared to Q-switched laser.Both methods are associated with minimal adverse reactions and comparable aesthetic satisfaction.
