what is ceramide powder?
Ceramide Powder is a type of natural oil found in our skin, and they are extremely important for the skin. Ceramides are composed of several lipid components, such as phospholipids, glycolipids, and sphingolipids, among others. In particular, this sphingolipid can help the skin retain moisture, allowing the skin to remain hydrated and soft. Sphingolipids can facilitate the transmission of information between skin cells, enhance the synergy of cells, and make the skin healthier.

What is the function of ceramide powder?
1.Composing the skin barrier
The skin barrier includes physical, chemical, immune and microbial barriers, and the physical barrier is mainly composed of the stratum corneum and intercellular junctions. Cellular and intercellular lipids in the stratum corneum are involved in the "brick wall structure", and intercellular lipids mainly include ceramides, fatty acids, and cholesterol. The amphiphilic nature of ceramides allows barrier lipids to form a membranous intercellular lipid layer, whereas their hydrophilic groups promote epidermal hydration and prevent excessive transcutaneous water loss.
Ceramide powder can promote the synthesis of filaggrin (FLG), which is not only an important structural protein, but also the main source of moisturizing factors. FLG monomers polymerize to form keratin bundles, which participate in maintaining the structure and integrity of the stratum corneum. Filaggrin is decomposed into free amino acids and other natural moisturizing factors, including urea, sodium pyrrolidinone carboxylate, and lactic acid.
2.Signal transduction
Intracellular Ceramides can act as messengers Ceramides powder act as second messengers in various biological processes. Messenger ceramides are of similar origin to non-messenger ceramides, and there are no significant differences in chemical structures, including ω-O-acyl-very long chain ceramides that are unique to the epidermis. However, most of the precursors of non-messenger ceramides (glucosylceramide) are located in the lamina vesicles and cannot directly enter the cytoplasm to participate in signal transduction.
In addition to being fundamental structural parts of biofilms, lipids, including sphingolipids, are increasingly recognized as important regulators of many important cellular processes, including autophagy. Autophagy is an important mechanism to maintain cell self-stability and renewal under physiological and pathological conditions.
3.Regulation of skin immunity
Skin lipids play an important role in immune regulation and inflammatory response. Sphingosine, dihydrosphingosine and phytosphingosine have similar antibacterial activities against a range of Gram-positive and Gram-negative bacteria, including Escherichia coli, Fusobacterium nucleatum, Staphylococcus aureus, light Streptococcus, etc. The accumulation of sphingosine bases in bacterial cell membrane and the induction of bacterial ultrastructure damage are related to the insertion of sphingosine bases into the cytoplasmic membrane (Gram-positive and Gram-negative bacteria) and the polar lipids in the inner leaflet of the outer membrane (Gram-negative bacteria), resulting in the change of the physical properties of the bacterial cell membrane and the loss of membrane function.
