Ceramide is a type of amide compound formed by dehydration of long-chain fatty acids and the amino group of sphingosine. It mainly includes ceramide phosphocholine and ceramide phosphoethanolamine. Phospholipids are the main components of cell membranes. 40% to 50% of them in the stratum corneum. % of sebum is composed of ceramides, which are a major component of the intercellular matrix and play an important role in maintaining the moisture balance of the stratum corneum. Ceramide has a strong ability to associate with water molecules, and it maintains skin moisture by forming a network structure in the stratum corneum. Therefore, ceramides have the function of keeping skin hydrated.
1. Ceramide plays a very important role in maintaining skin barrier function.
2. Ceramide can significantly enhance the adhesion between keratinocytes, improve skin dryness, and reduce skin desquamation.
3. Ceramide has the function of maintaining skin moisture.
4. Ceramide can increase the thickness of the epidermal stratum corneum, improve the skin's water-holding capacity, reduce wrinkles, enhance skin elasticity, and delay skin aging.
5. Ceramide can regulate cell growth variation, induce cell apoptosis and other cellular functions.
1. Ceramide can be used in the pharmaceutical industry
2. Ceramide can be used in the cosmetics industry
