[Global Times Reporter Zhao Hua] According to a February 22 report by French ELLE magazine, the timing of facial cleansing impacts skincare efficacy and skin quality. The article notes that the skin's epidermis performs distinct functions during day and night. By day, it builds a defense system to shield against external irritants, while at night it activates regeneration to repair daytime damage.
Citing research from U.S.-based PureWow, the article explains that the epidermis's repair function, like bodily rhythms, follows a circadian cycle. As light dims, cells initiate regeneration. If skin isn't cleansed promptly, accumulated impurities can erode the skin's surface and hinder cellular repair. Therefore, cleansing should be completed as soon as possible after sunset.
Research from Spain's Barcelona Center for Genomic Regulation corroborates this, noting that promptly cleansing skin after dark effectively combats premature skin aging.
