摘要目的:为化妆品不良反应防治提供资料。方法:2013年1月至2017年10月，大连医科大学附属第二医院皮肤科收集化妆品不良反应患者的资料及化妆品使用信息，820例中男23例，女797例；年龄7～75(32.66±8.09)岁。对其中687例患者行化妆品斑贴试验进行分析。结果:820例化妆品不良反应患者中女性占97.20%，男性占2.80%。年龄分布以21～40岁中青年最常见，占71.34%。受教育程度以高等教育者最多，占59.69%。职业分布以职员和无业人员最多，分别占28.54%和18.66%。既往有化妆品过敏史占17.28%。化妆品不良反应的临床类型以化妆品接触性皮炎最常见，占92.70%。共涉及可疑致病化妆品1682种。化妆品原物斑贴试验阳性率42.39%；斑贴试验阳性的化妆品中，保湿类、抗皱类、美白祛斑类化妆品所占比例最高，分别为31.59%、15.09%、12.68%。结论:化妆品接触性皮炎是最常见的化妆品不良反应类型。行可疑致病化妆品原物斑贴试验对化妆品不良反应具有较高的诊断价值。

abstractsObjective:To provide epidemiological data and clinical evidence for cosmetic adverse reactions.Methods:A retrospective clinical analysis was carried out on a total 820 outpatients (23 males and 797 females) suspected to be with cosmetic adverse reactions from January 2014 - October 2017, and average age of these patients was 7~75 (32.66±8.09) years. Suspicious cosmetics patch tests were performed in some patients. Suspicious cosmetics patch tests were performed in 687 patients.Results:Among 820 patients with cosmetic adverse reactions, women accounted for 97.20% and men accounted for 2.80%. Age distribution was most common among young people aged 21-40 years, accounting for 71.34%. The highest level of education was higher education, accounting for 59.69%. Occupational distribution was most commonly concentrated in employees and unemployed persons, accounting for 28.54% and 18.66%, respectively. A history of cosmetics allergies accounted for 17.28%. Cosmetic contact dermatitis was the most common clinical type of cosmetic adverse reactions, accounting for 92.70%. A total of 1682 suspected pathogenic cosmetics were involved. The positive rate of the cosmetic original patch test was 42.39%. Among the cosmetics with a positive patch test, moisturizing, anti-wrinkle and whitening freckle cosmetics accounted for the highest proportion, 31.59%, 15.09%, and 12.68%, respectively.Conclusions:Cosmetic contact dermatitis is the most common type of cosmetic adverse reaction.
