Ceramides CAS 100403-19-8
The ceramides mixture consists of hydroxy and non-hydroxy fatty acid-containing ceramides. Ceramides are generated from sphingomyelin through activation of sphingomyelinases or through the de novo synthesis pathway, which requires the coordinated action of serine palmitoyl transferase and ceramide synthase. They have been shown to mediate antiproliferative responses such as apoptosis, growth arrest, differentiation, and senescence.

1.Moisturizing effect: ceramide is the main component of the skin stratum corneum lipid, can help repair the skin barrier can make the skin soft and shiny. But ceramide decreases with age, and skin without it becomes dull and dry.
2.Barrier effect: sufficient ceramide in the skin can resist external stimulation, but without or without, the skin will lose its natural protective effect, and there is no defense ability for all external physical, biological and other Chemicalbook damage. For example, the skin is more prone to sunburn when exposed to the sun, and it is easy to turn red when the weather becomes cold.
3.Anti-allergy effect: This is the Gospel for thin skin children's shoes, ceramide can help to thicken the stratum corneum, enhance the tolerance of the whole skin, protect against external harmful substances, avoid sensitivity, and repair the role of red blood.
4.In addition, ceramide has a very good anti-aging, auxiliary whitening and antioxidant effect.
