Ceramides are a family of waxy lipid molecules. A ceramide is composed of sphingosine and a fatty acid. Ceramides are found in high concentrations within the cell membrane of cells, since they are component lipids that make up sphingomyelin, one of the major lipids in the lipid bilayer. Contrary to previous assumptions that ceramides and other sphingolipids found in cell membrane were purely supporting structural elements, ceramide can participate in a variety of cellular signaling: examples include regulating differentiation, proliferation, and programmed cell death (PCD) of cells.
Ceramides may be found as ingredients of some topical skin medications used to complement treatment for skin conditions such as eczema.They are also used in cosmetic products such as some soaps, shampoos, skin creams, and sunscreens. Additionally, ceramides are being explored as a potential therapeutic in cancer .
Naturally occurring, long chains of lipids (fats) that are major components of skin’s outer layers. Skin inhibits water movement via its structure, which has a unique composition of 50% ceramides, 25% cholesterol, and 15% free fatty acids.
Ceramides are necessary for their water-retention capacity and adding them to a skincare product helps provide replenishing and restoring benefits.
1.Ceramide is the main component of the stratum corneum of the epidermis layer of human skin.
2. Together with cholesterol and saturated fatty acids, ceramide creates a water-impermeable, protective organ to prevent excessive water loss due to evaporation as well as a barrier against the entry of microorganisms.
3.With aging there is a decline in ceramide and cholesterol in the stratum corneum of humans.
4.Ceramides may be found as ingredients of some topical skin medications used to complement treatment for skin conditions such as eczema. They are also used in cosmetic products such as some soaps, shampoos, skin creams, and sunscreens.
5.Additionally, ceramides are being explored as a potential therapeutic in cancer .
Ceramide is the most recent years developed a new generation of moisturizing agent is a lipid soluble substance, it constitutes the physical structure of the stratum corneum of skin similar to quickly penetrate the skin, and cuticle of the water, forming a kind of network structure, to seal in moisture. Increase with age and into old age, exist in human skin will gradually reduce ceramide, dry skin and rough skin, skin type and other abnormal symptoms appear is due to a decrease in the amount of ceramide. So to prevent such skin abnormalities, added ceramide is an ideal way.
Taking ceramide, absorbed in the small intestine and transferred to the blood, and then transported to the body, so that the skin cells to obtain a good recovery and regeneration, but also allows the body's own neural acid biosynthesis.
