Ceramide can become a hot cosmetic raw material mainly because of its strong moisturizing and repairing effect. It is a kind of phospholipid with ceramide as the skeleton, mainly including ceramide phosphocholine and ceramide phosphoethanolamine. Phospholipid is the main component of cell membrane. 40% - 50% of the sebum in the cuticle is composed of ceramide. Ceramide is the main part of the intercellular matrix, which can maintain Cuticle water balance plays an important role. Ceramide has a strong ability to bind water molecules. It maintains skin moisture by forming a network structure in the cuticle. Therefore, ceramide can keep skin moisture.
Efficacy of ceramide as cosmetic raw material:
1. Barrier function: ceramide plays an important role in maintaining skin barrier function.
2. Adhesion: the main cause of skin dryness is the decrease of ceramide content in cuticle, which is directly related to the degree of skin dryness. Ceramide can obviously enhance the adhesion between keratinocytes, improve the dryness of skin and reduce the desquamation of skin.
3. Moisturizing effect: ceramide has a strong ability to bind water molecules. It maintains skin moisture by forming a network structure in the cuticle. Therefore, ceramide can keep skin moisture.
4. Anti-aging effect: ceramide can increase the ceramide content in the cuticle, improve the dry, desquamation, rough and other conditions of the skin; at the same time, ceramide can increase the thickness of cuticle, improve the water holding capacity of the skin, reduce wrinkles, enhance the elasticity of the skin, and delay the aging of the skin.
