The structure of human skin is divided into epidermis, dermis and subcutaneous tissue. The epidermal layer is the skin condition we see daily, from the inside to the outside, it is the stratum corneum, the transparent layer, the granular layer, the spinous layer and the basal layer. The function of the stratum corneum is to protect against external stimuli, while the granular layer perfects the skin environment. The spinous layer helps prevent foreign bodies from invading, and the basal layer can generate new cells. Ceramide is the lipid that exists in the outermost periphery of our skin and in the cells of the stratum corneum. To use a simple analogy, when building a house and building a wall, cement is used to layer the bricks one after another. Ceramide acts as a layer in the stratum corneum. It acts like cement, consolidating the structure of the entire surface layer, and accounts for about 40% to 55% of the lipid content. It not only locks moisture, preserves grease, but also maintains the integrity of lipids. The main effects of ceramide on the skin are:

Plain face), psoriasis, eczema, red blood streaks, sensitive skin, dry skin, rough skin, etc. The ceramide content of these problem skins is significantly lower than normal skin, so additional supplements are needed.
