Maintaining skin barrier integrity requires a systematic approach to water retention, making a hydration focused K-beauty routine a primary strategy for preventing transepidermal water loss (TEWL). When the stratum corneum (the outermost layer of the skin) lacks sufficient moisture, the structural cohesion of intercellular lipids is compromised, leading to increased sensitivity and a dull appearance.
