| what is ceramide? | ceramide (Ceramide) is a class of phospholipids with ceramide as the skeleton, mainly ceramide phosphocholine and ceramide phosphoethanolamine. Phospholipids are the main components of cell membranes. The 40% ~ 50% sebum in the stratum corneum is composed of ceramide. Ceramide is the main part of the intercellular matrix and plays an important role in maintaining the balance of water in the stratum corneum. Ceramide has a strong ability to associate water molecules. It maintains skin moisture by forming a network in the stratum corneum. Therefore, ceramide has the effect of maintaining skin moisture. Ceramide is the latest generation of humectant developed in recent years. It is a water-soluble lipid substance. It has a similar structure to the material that constitutes the stratum corneum of the skin. It can quickly penetrate into the skin and combine with the water in the stratum corneum to form a network structure that locks moisture. ceramide is the main component (>50%) of the intercellular lipid body of the stratum corneum that exists on the outermost side of human skin. it plays an important role in preventing water emission and protecting external stimuli. it plays an important role in protecting skin, moisturizing and moisturizing. There are also many research reports that the use of ceramide-containing topical ointment products can achieve the purpose of preventing allergic skin diseases and inhibiting melanin brown spots. With the increase of age and entering old age, the ceramide in human skin will gradually decrease, and the appearance of abnormal skin symptoms such as dry skin and rough skin is also due to the decrease in the amount of ceramide. |
| species | from its chemical structure, ceramide is composed of sphingosine long-chain bases (accounting for ~ 50% of the structure) and a fatty acid. Different sphingosine bases and fatty acid combinations form different ceramides. At present, 9 naturally formed ceramides have been discovered. In addition, there are plant ceramide (phytoceramides), ceramide (psuedoceramides) and synthetic ceramide (synthetic ceramides). ceramide: a wax lipid naturally found in the skin. It consists of a long chain of sphingosine bases and a fatty acid. Plant ceramide: The sphingosine bases that make up it are commonly found in the cell tissues of yeast, plants and some mammals. Don't be confused by the word "plant" in the name. Ceramide: It is also a lipid with similar properties but different structure to ceramide. For example, ceramide E and arachidamide MEA are both ceramides. Ceramides are usually synthetic, but they may also have natural forms. Synthetic ceramide: synthetic naturally occurring ceramide. In most cases, the ceramide used in cosmetics is synthetic (whether it is ceramide or ceramide), because the ceramide content in plants is too low and it is too expensive to extract from animals. Whether it is synthetic or natural extraction, as long as the chemical structure is the same, the same effect can be achieved. |
| the effect of ceramide on skin | ceramide is a lipid naturally pure in skin. Ceramide forms a waterproof barrier on the skin surface. They can not only help the skin lock in moisture, but also promote the self-repair of the skin barrier and regulate skin cells. The skin of newborn babies is often wrapped in a layer of waxy substance. This substance is called fetal fat and is mainly composed of ceramide, which can prevent skin water loss. The secretion of ceramide in the skin decreases with age, which in turn causes dry skin, wrinkles and some skin inflammation. 1, moisturizing effect: ceramide is the main component of the skin stratum corneum lipid, which can help repair the skin barrier and make the skin soft and shiny. But with age, ceramide gradually decreases, and the skin becomes dull and dry without it. 2. Barrier function: sufficient ceramide in the skin can resist external stimulation, but if it is missing or not, the skin loses its natural protective function and has no defense capability for all injuries such as external physics and biology. For example, skin is easy to sunburn when exposed to sunlight, and it is easy to turn red when the weather gets cold, etc. br>3. anti-allergic effect: this is a good news for children's shoes with thin skin. ceramide can help thicken stratum corneum, improve the tolerance of the whole skin, protect against the invasion of harmful substances from the outside, avoid the occurrence of sensitivity, and repair red blood streaks. 4. in addition, ceramide has very good anti-aging, auxiliary whitening and antioxidant effects. |
