Moisturizing effects
Ceramide has a strong ability of association of water molecules , it is to maintain the moisture of the skin through the mesh structure formed in the stratum corneum .
Ceramide can form a network structure in the stratum corneum water molecules in association to maintain skin moisture . Therefore , ceramide skin has a strong moisturizing effect.
Anti-aging effects
Skin aging process, lipid synthesis decreased ceramide content in the stratum corneum decrease the performance of dry skin, scaling , rough and dull ; make use of ceramide in the stratum corneum ceramide levels increased, dry skin can be improved , scaling, roughness and other symptoms ; Meanwhile , ceramide can increase the thickness of the stratum corneum , improve water-holding capacity of the skin, reduce wrinkles , increase skin elasticity , delay skin aging.
