[摘 要] 广义的皮肤屏障包括物理屏障、神经屏障、色素屏障及免疫屏障。 狭义的皮肤屏障通常指表皮屏障。 既往研究主要集中在角质层,忽视了表皮其他层次的屏障修复。 近年研究表明,多种皮肤疾病及皮肤问题的表皮屏障受损不仅在角质层,还涉及颗粒层、棘层及基底层,且角化包膜、细胞间脂质及紧密连接蛋白变化也是表皮屏障受损的关键因素。 但迄今为止,仍缺乏对表皮屏障不同层次受损机制及干预的系统探讨。 本文提出“表皮屏障受损及分层修复”新理念,为表皮屏障受损不同层次的精准修复提供理论依据及临床应用新视角。

[Abstract] The skin barrier in a broad sense includes the physical barrier, neural barrier,pigment barrier, and immune barrier, while the skin barrier in a narrow sense generally refers to the epidermal barrier. Previous studies have mainly focused on thestratum corneum, neglecting barrier repair in other epidermal layers. Recent studies have revealed that epidermal barrier damage in various dermatoses and skin conditions involves not only the stratum corneum but also the stratum granulosum, stratum spinosum, and stratum basale, with alterations in the cornified envelope, intercellular lipids, and tight junction proteins being key contributing factors. However, systematic investigations into the damage mechanisms and targeted interventions for different epidermal barrier layers remain lacking. This article proposes the new concept of “ epidermal barrier damage and stratified repair ”, providing both a theoretical framework and new clinical insights for layer⁃specific precision repair of the epidermal barrier.
