神經醯胺（Ceramide）又名分子釘或賽洛美，為角質層細胞間脂質的主要成分，占比約 50%，神經醯胺的結構組成是很複雜的，皮膚中神經醯胺約有 300 多至 1000 種的變化。由於其同時具有親水與親油的特性，所以能夠形成脂質雙層的結構，加了間質的柔軟度與保水能力。人體皮膚的神經醯胺也會隨著時間而流失，而造成雙脂質層的結構紊亂，進而使肌膚屏障的能力下降。
神經醯胺1型(Ceramide I )、神經醯胺2型(Ceramide II)
Ceramide occurs naturally in our skin, is one of the nine lipids that present in the epidermis. The lipid is on the top layer of the skin, and is to prevent water loss and losing moisture. Studies indicate a positive relationship between aging and the loss of ceramide in epidermis. Patients often suffer from skin dryness, itching, flaking, peeling or even severe skin disorders. By applying ceramide skin care products can help repair the lipids that have been lost due to chronic dryness, environmental factors, and skin damage caused by certain skin conditions.
Ceramides are the major lipid constituent of lamellar sheets present in the intercellular spaces of the stratum corneum. These lamellar sheets are thought to provide the barrier property of the epidermis. It is generally accepted that the intercellular lipid domain is composed of approximately equimolar concentrations of free fatty acids, cholesterol, and ceramides. Ceramides are a structurally heterogeneous and complex group of sphingolipids containing derivatives of sphingosine bases in amide linkage with a variety of fatty acids. Differences in chain length, type and extent of hydroxylation, saturation etc, are responsible for the heterogeneity of the epidermal sphingolipids. It is well known that ceramides play an essential role in structuring and maintaining the water permeability barrier function of the skin.
According to dermatological studies, patients between 40 to 50 years old contain only 30% to 40% of ceramide in the epidermis. Skin disorders such as psoriasis, ichthyosis, acne, and atopic dermatitis are triggered due to the lacking of ceramide. Applying ceramide skin-care products daily can prevent water loss.
HYALURONIC ACID STORY
Hyaluronic Acid is naturally found in human body. It notonly help cushion and lubricate joints, but is also a major component of skintissue. As one of the Natural Moisturizing Factors in human skin, Hyaluronic Acid plays an important role of keeping the skin moisturized and bountiful. The loss of Natural Moisturizing Factors is correlated with chronically aging, environmental factors, personal behaviors that lead to various skin problems anddisorders.
Hyaluronic Acid is known to be able to carry hundreds or thousands times of its weight in water. Applying Hyaluronic Acid on the skin is capable of acquiring water molecules in the surrounding and furthermore penetrates and supplies water into the skin. Hyaluronic Acid is now recognized one of the best moisture products.
