Ceramide

Description

What are Ceramides?

Ceramides, also known as sphingolipids, are lipids that exist in the skin and play an important role in the formation of the epidermal stratum corneum. It is a structural unit shared by (neural) sphingolipids. The fatty acid has an acid amide bond structure on the amino group of sphingosine. If sugar is bound to it, it becomes glycosphingolipids, and if phosphorylcholine is bound, it becomes (sphingomyelin). Ceramide is an intermediate metabolite of sphingolipids, especially occupies an important position in biosynthesis.

Moisturizing effect

The moisture content of the skin is about 18%-20% of the body weight. Skin moisturization and elasticity are closely related to the moisture content of the epidermis. Excessive loss of skin moisture can lead to dryness and even chapped skin. The lipid components extracted from the stratum corneum of the epidermis were subjected to local skin tests under the same conditions to explore which lipid component can have and what effect on skin moisture recovery. It was found that the topical use of ceramide can significantly increase the electrical conductivity of the skin, followed by cholesterol, and the effects of free fatty acids and cholesterol esters are not obvious. Ceramide has a strong ability to associate water molecules. It maintains skin moisture by forming a network structure in the stratum corneum. Therefore, ceramide has the effect of keeping skin moisture.

Anti-aging effect

During the aging process of the skin, lipid synthesis decreases and the ceramide content in the stratum corneum decreases. The characteristics of skin aging are as follows: 

(1) Dry skin, desquamation, roughness, and loss of luster; 

(2) Thinning of the skin stratum corneum, increased wrinkles, and decreased elasticity. The use of ceramide can increase the content of ceramide in the epidermal stratum corneum, which can improve skin dryness, desquamation, roughness and other conditions; at the same time, 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.

Ceramides for Skin

Ceramide is the latest generation of humectant developed in recent years. It is a water-soluble lipid substance. It has a similar structure to the material that constitutes the stratum corneum. It can quickly penetrate into the skin and combine with the water in the stratum corneum to form a A net-like structure that locks in moisture.
