Product Description
Ceramide NP, also known as ceramide 3, is a lipid substance that is an important ceramide subclass in the stratum corneum of the skin.
I. Structure and Source Structure : Ceramide NP is composed of plant sphingosine and hydroxyl free fatty acids, which are linked by amide bonds. Source : Ceramide NP can be synthesized and is also found in human skin.
2, function and efficacy Moisturizing and locking water : Ceramide NP can quickly penetrate the skin and combine with the water in the stratum corneum to form a network structure that locks in water and strengthens the adhesion between the stratum corneum cells, thereby improving the degree of skin dryness and reducing skin scaling.
