What is the main role of ceramide in Ceramide Repairing Facial Serum in the skin?

Barrier effect: Ceramide in Ceramide Repairing Facial Serum is an important component of the skin's stratum corneum, accounting for about 40% to 50% of the lipids in the stratum corneum. It can form a mesh structure in the stratum corneum to help the skin lock in moisture and prevent moisture loss, while resisting external environmental stimuli such as ultraviolet rays, dust, bacteria, chemicals, etc. This barrier effect helps maintain the moisture balance of the skin and keep the skin healthy.
Adhesion effect: Ceramide binds cells to proteins on the cell surface through ester bonds, enhancing the adhesion between cells. When the ceramide content in the epidermal stratum corneum decreases, the adhesion between keratinocytes decreases,resulting in problems such as dry skin, desquamation, and scaling.
Repairing the skin barrier: Timely supplementation of sufficient ceramide can improve problems such as dry skin and desquamation, and help repair damaged skin barrier function. The repairing effect of ceramide can strengthen the skin's own defense ability and reduce the damage to the skin by the external environment.
Anti-aging effect: Ceramide can increase the ceramide content in the stratum corneum and improve skin dryness, desquamation, roughness and other conditions. It can enhance the skin's water holding capacity, reduce wrinkles, and enhance skin elasticity, thereby delaying skin aging.
Moisturizing effect: Ceramide has good moisturizing properties. It can maintain moisture in the skin by forming a mesh structure in the stratum corneum. This moisturizing effect helps to keep the skin moisturized and makes the skin look more shiny.
In summary, the main roles of ceramide in the skin are barrier effect, adhesion effect, skin barrier repair, anti-aging effect and moisturizing effect. These effects work together to maintain the health of the skin, keeping the skin moisturized, smooth and elastic.
