Ceramide (pronounced ser-A-mid OR seramide) is a family of lipid molecules. A ceramide is composed of sphingosine and a fatty acid. Ceramides are found in high concentrations within the cell membrane of cells. They are one of the component lipids that make up sphingomyelin, one of the major lipids in the lipid bilayer. For years, it was assumed that ceramides and other sphingolipids found in the bilayer cell membrane were purely structural elements. This is now known to be not completely true. Ceramide can actually act as a signaling molecule. The most well-known functions of ceramides as cellular signals include regulating the differentiation, proliferation, programmed cell death (PCD), and apoptosis (Type I PCD) of cells.
1. Moisturizing effect
Ceramide has a strong ability to associate water molecules, and it maintains the moisture of the skin through the network structure formed by the stratum corneum.
Ceramides can form a network in the stratum corneum water molecules to keep the skin hydrated. Therefore, ceramide skin has a strong moisturizing effect.
2. Anti-aging effect
In the process of skin aging, lipid synthesis decreases, and the content of ceramide in the stratum corneum decreases, which is manifested as dry skin, scaling, roughness and dullness; the use of ceramide to increase the level of ceramide in the stratum corneum can improve dry skin, Scaling, roughness and other symptoms; at the same time, ceramide can increase the thickness of the stratum corneum, improve the skin's water retention capacity, reduce wrinkles, increase skin elasticity, and delay skin aging.
3. Anti-allergic effect
There are many reasons for skin allergies. According to official reports, more than 70% of skin care and beauty cosmetics are caused by skin allergies.
