Ceramide is a kind of sphingosine lipid composed of sphingosine long-chain bases and fatty acids. Ceramide is a kind of phospholipid with ceramide as the skeleton, mainly including ceramide choline phosphate and ceramide ethanolamine phosphate. Phospholipid is the main component of cell membrane. 40% ~ 50% of sebum in stratum corneum is composed of ceramide. Ceramide is the main component of intercellular matrix and plays an important role in maintaining the water balance of stratum corneum. Ceramide has a strong ability to bind water molecules. It maintains skin moisture by forming a network structure in the stratum corneum. Therefore, ceramide has the function of maintaining skin moisture.
1. Barrier effect
Experimental studies show that ceramide plays a very important role in maintaining skin barrier function.
Experimental studies show that the content of ceramide is directly related to the degree of skin dryness. The use of ceramide can significantly enhance the adhesion between keratinocytes, improve the dryness of skin and reduce skin desquamation.
3. Moisturizing effect
Ceramide has a strong ability to associate water molecules. It maintains skin moisture by forming a network structure in the stratum corneum. Therefore, neurophthalamine has the function of maintaining skin moisture.
4. Anti aging effect
Ceramide can improve dry, desquamate and rough skin; At the same time, ceramide can increase the thickness of epidermal stratum corneum, improve skin water holding capacity, reduce wrinkles, enhance skin elasticity and delay skin aging.
5. Cell function
Some experimental studies have shown that ceramide can regulate cell growth variation and induce apoptosis.
1. Daily chemical aspect
Using the skin essence cosmetics containing neurophthalamine can strengthen the anti-aging function of the skin, keep the skin elastic, smooth and meticulous, and reduce the formation of facial wrinkles.
2. Medical aspect
Ceramide plays an important messenger role in the biological effects induced by a variety of cytokines, vitamin D3, Fas and CD28 ligands, and its role in mediating apoptosis has attracted more and more attention; At the same time, ceramide is also involved in many physiological and pathological processes such as cell differentiation. Ceramide can induce apoptosis in epidermal keratinocyte culture. Ceramide is the decomposition product of sphingomyelin in biofilm bilayer and is recognized as the second messenger; Ceramide plays an extensive and important role in the process of cell growth, proliferation, differentiation, apoptosis and injury.
3. Food industry
Many health foods have been developed by using some physiological functions of ceramide, which can inhibit the rise of blood pressure, activate immunity, hinder lipase activity, inhibit the proliferation of cancer cells and so on. Plant ceramide products were also officially commercialized to the market in 1998. So far, its commodities are mainly functional drinks, tablets and other nutritional supplements and health food, and there are few commodities that actually feel effective.
