Sweet, spicy or greasy food, staying up late, and using electronic products for a long time are common bad habits nowadays. Their role in skin diseases has been paid much attention.
The aim of this study was to investigate whether unhealthy lifestyles would affect the skin sebum content, SC hydration, and pH and how do they affect.
A total of 300 volunteers were enrolled, and a multifunctional skin physiology monitor measured the three skin biophysical properties on the forehead and dorsal hand. Lifestyle factors were evaluated by a self-administered questionnaire.
Eating oily, sweet, spicy food, and staying up late increased the sebum content of the forehead significantly. Dorsal hand SC hydration was higher in people eating more sweet food and oily food, and forehead SC hydration was higher in people eating more sweet food and go to bed earlier. Eating sweet food could increase pH in both forehead and dorsal hand. The forehead pH decreased in using electronic products over 6 hours a day or staying up late. There are significant differences in sebum, hydration, and pH value among different age groups. In males, the pH was lower than females, but the sebum was higher.
Sebum content, SC hydration, and pH are affected by unhealthy lifestyles, age, and gender.
甜食、辛辣或油腻食物、熬夜以及长时间使用电子产品是如今常见的不良习惯。它们在皮肤病中的作用已受到广泛关注。
本研究旨在调查不健康的生活方式是否会影响皮肤皮脂含量、皮肤角质层水合作用及pH值，以及如何产生影响。
共招募300名志愿者，使用多功能皮肤生理监测仪测量其前额和手背部的三项皮肤生物物理特性。通过自填式问卷评估生活方式因素。
食用油腻、甜食、辛辣食物以及熬夜会显著增加前额的皮脂含量。食用较多甜食和油腻食物的人，手背部皮肤角质层水合作用较高；食用较多甜食且早睡的人，前额皮肤角质层水合作用较高。食用甜食会使前额和手背部的pH值升高。每天使用电子产品超过6小时或熬夜会使前额pH值降低。不同年龄组在皮脂、水合作用和pH值方面存在显著差异。男性的pH值低于女性，但皮脂含量高于女性。
皮脂含量、皮肤角质层水合作用及pH值受不健康生活方式、年龄和性别的影响。
