Water is the fountain of life, anile body will gradually lose moisture, “hyaluronic acid” is the most important material to retain moisture in human tissue. The hydration of this mucopolysaccharide and protein makes the body tissue maintaining large amounts of water. Skin also contains a large amount of hyaluronic acid, the content will decrease with the age increased, causing skin dry and wrinkles produce.
Hyaluronic acid is a natural polysaccharide, transparent appearance, sticky gelatinoid. Filling in the space of body cells and collagen fibers, and covered in some connective tissues. Hyaluronic acid not only have the function of maintaining skin elasticity, but also can lock a large number of water molecules, has a moisturizing lubrication effect on the organization, it also the component of the eye lens, joint lubricating fluid and other substances. It is often used to make cosmetics as well as the drugs of treating arthritis and cataracts and other diseases.
The origin of hyaluronic acid
Hyaluronic acid, also known as uronic acid, which is naturally present and essential in human tissue, the average molecular weight betweens in 1 million to 10 million Dalton. Has a very important function on maintaining the overall organizational structure, and the transportation between cells. In nature, hyaluronic acid was widely existed in the connective tissue, mucus tissue and eye lens of vertebrates as well as capsule of some bacteria. No matter the hyaluronic acid derive from which tissues, its chemical composition and structure is the same. Its biological compatibility, absorbability makes hyaluronic acid as medical polymer material has the advantages of without immune response, material can be decomposed by living body and absorbed.
Several formulations of hyaluronic acid plus basic auxin can enhance fracture recovery, the recent experimental results by pharmaceutical raw materials suppliers demonstrated that the oligosaccharide of hyaluronic acid may be possible to suppress the expansion of a certain kind of cancer cell, this oligosaccharide sticks at the cell surface and blocking the hyaluronic acid receptor on the cell surface. This cell surface hyaluronan receptor is an important pipeline of cancer cells growth.
Hyaluronic acid is abounding in human connective tissue and dermis, a kind of transparent gelatinous substance, which full absorbed moisture, can be regarded as the skin moisturizing factor. Appropriately supplying hyaluronic acid will not only help the skin absorbing a lot of moisture from the body and the skin’s surface, but also enhance the skin’s water remaining capacity for a long time. When the hyaluronic acid absorbing a lot of water, the elastic fibers and collagen in a full of moisture environment, then the skin will be more flexible. Young skin is rich in hyaluronic acid, so it was soft and elastic. While the hyaluronic acid will be lost with the age increased, result in losing skin moisture, and the skin losing elasticity and luster, for a long time, the skin will appear wrinkles.
In the early 1980s, excellent moisturizing function of hyaluronic acid has been gained extensive attention in the international cosmetics industry. Hyaluronic acid applied on the skin can absorb large amounts of water, no matter it was used in what kind of humidity, climate, environment, skin types, it has the same water-retaining property. Its practical effect over the stratum corneum hydration, so hyaluronic acid is an ideal moisturizing ingredients for very dry or aging to severe water shortages skin. The water content of normal cuticle was between 10-15% around. If the moisture content is below 10%, the skin will be dry peeling, also further result in dermis tissue losing water, form of wrinkles relaxation. Hyaluronic acid can increase the moisture content of the skin, keep the skin moist and humidity, elastic and shiny, retains skin moisture to achieve long-term moisturizing.
