What is An Optimal Method for Quantifying the Facial Sebum Level and Characterizing Facial Sebum Features about?

## Abstract ## Background Evidence suggests that sebum content is important in skin disorders such as acne. However, sebum levels change depending on the external environment, and quantifying skin sebum levels is challenging. Here, we propose an optimal method for quantifying the facial sebum level. ## Materials and methods Four hundred and sixty participants (160 males and 300 females) aged 20–40 were enrolled in this study. A Sebumeter SM 810 was used to measure the sebum level at five facial locations: the forehead, the chin, the left cheek, the right cheek, and the nose. The participants were divided into two groups; one group underwent a one‐time measurement (__n__ = 390, male: female = 120: 270), and the other underwent three consecutive measurements (__n__ = 70, male: female = 40: 30). The casual sebum level (CSL) was measured in all patients after a 30‐min acclimatization; subsequently, the sebum removal process was conducted, followed by a resting period of 1 h to determine the sebum excretion rate (SER). Spearman's correlation analysis and the Wilcoxon signed‐rank test were used to compare the sebum level consistency and differences between the groups. ## Results Although
