Abstract

Epidermal turnover time is the time taken for the epidermis to replace itself. The turnover time can be subdivided; when the epidermis is divided into proliferative compartment, differentiated compartment, and stratum corneum, the total turnover time is the sum of the turnover time of each compartment. Using Weinstein's data (J Invest Dermatol 82: 623-628, 1984), the epidermal turnover time was calculated to be 47-48 days instead of 39 days.

摘要

表皮更替时间是表皮自我更新所需的时间。更替时间可以细分；当表皮分为增殖区室、分化区室和角质层时，总更替时间是每个区室更替时间之和。根据温斯坦的数据（《皮肤病学研究杂志》82:623 - 628,1984），计算得出表皮更替时间为47 - 48天，而非39天。
