Melasma treatment is difficult due to extended treatment periods, suboptimal adherence, inconsistent results, and frequent relapses. Kojic acid has been shown to be effective in reducing melasma severity and is now increasingly used in cosmetic treatments.
The purpose of the present study was to evaluate the effectiveness of a new cosmetic treatment for melasma at 45 and 90 days.
Multicenter prospective study across 20 dermatology clinics/ambulatories. One hundred patients with mild-to-moderate melasma were evaluated. The primary endpoints were changes in mean modified melasma area and severity index (mMASI) score and patient-reported satisfaction at 45 and 90 days.
The mean age of patients was 45.19 ± 11.5 years. Most patients were female and Caucasian. Patients presented mixed (65%), epidermal (26%), and dermal (4%) types of melasma. Triggering factors were hormonal contraception (33%), pregnancy (31%), and pharmacological treatment (11%); mean disease duration was 6.7 ± 6.8 years. Overall, a statistically significant decrease in mean mMASI scores was seen at 45 (2.19 ± 0.182 vs 3.29 ± 0.267, P < .0001) and 90 days (1.27 ± 0.128 vs 3.29 ± 0.267, P < .00001). The highest reduction in mMASI scores was observed in patients with dermal melasma. IGA scores showed a statistically significant improvement in pigmentation at 90 days (P < .00001).
The novel cosmetic treatment was associated with the improvement of melasma, as assessed by mMASI.
黄褐斑的治疗颇具难度,原因在于治疗周期长、依从性欠佳、效果不稳定以及频繁复发。已证实曲酸在减轻黄褐斑严重程度方面有效,如今在美容治疗中使用得越来越多。
本研究旨在评估一种新型美容疗法在45天和90天时治疗黄褐斑的效果。
在20家皮肤科诊所/门诊进行多中心前瞻性研究。对100例轻至中度黄褐斑患者进行评估。主要终点为45天和90天时平均改良黄褐斑面积和严重程度指数(mMASI)评分的变化以及患者报告的满意度。
患者的平均年龄为45.19±11.5岁。大多数患者为女性且是白种人。患者呈现混合型(65%)、表皮型(26%)和真皮型(4%)黄褐斑。诱发因素为激素避孕(33%)、妊娠(31%)和药物治疗(11%);平均病程为6.7±6.8年。总体而言,45天时平均mMASI评分有统计学意义的下降(2.19±0.182对3.29±0.267,P<.0001),90天时也有下降(1.27±0.128对3.29±0.267,P<.00001)。真皮型黄褐斑患者的mMASI评分下降最为明显。IGA评分显示90天时色素沉着有统计学意义的改善(P<.00001)。
通过mMASI评估,这种新型美容疗法与黄褐斑的改善相关。
