The stratum corneum is the outermost part of the epidermis, skin moisture retention is determined by the water content of the stratum corneum, that is, whether our skin is dry, depending on this layer. In the stratum corneum, keratinocytes and intercellular lipids are arranged in a brick wall-like structure, forming a stable skin structure that protects the skin’s barrier function, effectively preventing excessive evaporation of water from the body while preventing the invasion of bacteria or foreign substances into the body. In a nutshell, the skin barrier consists of the most superficial layer of the skin, which is the surface of the skin visible to the naked eye. Its function is to keep the skin moist and smooth, and to shield it from harmful substances.
