With the public's interest in skincare increasing over the years, many studies have been conducted on the effects of LED masks and functional cosmetics on skincare issues such as enlarged pores, excess sebum secretion, etc. However, most studies were carried out within 4 weeks, which is a quite short period of time, as well as neglected factors such as age, gender, and skincare methods (mixed, single) and thus lack reliability in their findings. Hence, based on empirical data, this study analyzed the main effects of LED masks and functional cosmetics under various conditions on facial skin over a 12-week period. Results of the analysis show that the main effects of the items on facial skin under various monitored conditions are empirically significant. [ABSTRACT FROM AUTHOR] |
