To study lip hydration levels when applying a lipstick sunscreen for 3 months and to evaluate the influence of size of lips, age, sex, smoking and skin phototype.
The study group was formed by 140 volunteer subjects, one group consisting of 70 patients applying a commercial lipstick sunscreen three times a day and the other group of 70 controls in which no product was applied. The age range was 20-86 years. The influence in lip hydration levels of age, sex, phototype, size of the lips and smoking habits was studied using a Corneometer 825 (Courage & Khazaka Electronic GmbH, Cologne, Germany).
An increase in lip hydration was found between the basal (53.49 +/- 15.259) and final (59.34 +/- 14.51) Corneometer 825 (Courage & Khazaka Electronic GmbH, Cologne, Germany) measurements over the three months of treatment, with statistically significant differences with respect to the control (p=0.002). However, no statistically significant differences in lip hydration were observed with regard to age, (p=0.48), gender (p=0.876), skin phototype (p=0.653), lip area (p=0.291) and smoking (p=0.178).
Application of a lipstick sunscreen 3 times a day for 3 months increases lip hydration.
研究涂抹口红防晒霜 3 个月后嘴唇的水分水平，并评估嘴唇大小、年龄、性别、吸烟和皮肤光型的影响。
研究组由 140 名志愿者组成，一组 70 名患者每天涂抹三次商业口红防晒霜，另一组 70 名对照者不涂抹任何产品。年龄范围为 20-86 岁。使用 Corneometer 825（Courage & Khazaka Electronic GmbH，科隆，德国）研究年龄、性别、光型、嘴唇大小和吸烟习惯对嘴唇水分水平的影响。
在治疗的三个月中，Corneometer 825（Courage & Khazaka Electronic GmbH，科隆，德国）的基础（53.49 +/- 15.259）和最终（59.34 +/- 14.51）测量值之间发现嘴唇水分增加，与对照组相比具有统计学显著差异（p=0.002）。然而，在嘴唇水分方面，年龄（p=0.48）、性别（p=0.876）、皮肤光型（p=0.653）、嘴唇面积（p=0.291）和吸烟（p=0.178）均无统计学显著差异。
每天涂抹口红防晒霜 3 次，持续 3 个月，可增加嘴唇水分。
