Hyaluronic acid can really wrinkle?

Hyaluronic acid is used of road "as God used to manufacture of Adam and Eve's clay, many Hollywood actress if you do not have it, they may die.

" In the big S beauty King 2" in the hero "save us" it was none other than hyaluronic acid.

Hyaluronic acid (Hyaluronicacid, HA) a glassy uric acid, is a cosmetic advertising flyers.

1937, Columbia University, Professor Meyer in ophthalmology, for the first time in isolation in bovine vitreous has hyaluronic acid. In the subsequent study, scientists found that it is made from glucuronic acid and acetyl Glucosamine two Monosaccharides one another aggregating the noncyclic macromolecules polysaccharides. In aqueous solution, hyaluronic acid of sugar chains are horizontal in Crosslinking network, like a sponge, absorbing and keep large amounts of water.

In fact, hyaluronic acid is a natural component in the human body.

It is estimated that an adult's body contains about 15 grams of hyaluronic acid. It has played the most important function is the function of water. With age, hyaluronic acid. If the 20-year-old body hyaluronic acid relative content set to 100, 30, 50, 60 years old, this number decreased to 65, 45, 25. Skin also becomes rough and wrinkles.

When the wonderful effects of hyaluronic acid has been excavated, quickly became the incumbent "beauty."

Injection, topical and oral, is beauty with hyaluronic acid in three main ways.

Injectable hyaluronic acid in 2003 was beautiful and medicinal Bureau (FDA) approval for skin wrinkle.

In simple terms, is where you want to play with convex, and quick to act. More worthy of praise, as hyaluronic acid are body composition, biocompatibility. Injection of hyaluronic acid in the body to be slowly and original fusion of hyaluronic acid, then be slowly metabolism, each can be maintained for 6 months to 1 year. It is important to note that when used for injection must be selected high-purity products, otherwise the impurities is likely to trigger an immune response, but instead let users suffer negative consequences.

Hyaluronic acid moisturizing properties of the external-type of skin care products is also a large number of applications.

Some manufacturers even offer hyaluronic acid solution for consumers to use. Its density is high, generally after use without dilution. Working directly with a high concentration of the solution will not be played on facial skin moisturizing effects, but also because hyaluronic moisture absorption effect of moisture absorption to the original skin.

However, the injection of hyaluronic acid wrinkle is a result of physical effects.

External use, its molecules are almost not likely to be absorbed through skin and will not be able to play the role of the injection time. It's good for the skin provides a rich environment that can prevent the drying of the external environment on the skin of adverse effects from an objective point of view with anti-wrinkle effect, but for existing wrinkles, external effects of hyaluronic acid.

Some callouts containing hyaluronic acid components of health care products in the propaganda claimed the role of the "skin", the reason some oral intake of hyaluronic acid as the circulatory system located in the epidermis and DermIS, compensate for the lack of original; also some think after oral administration of products through the decomposition will increase when the precursors of hyaluronic acid synthesis, which increases skin Office content.

Former reason almost not worth refuting, hyaluronic acid-molecular-weight in hundreds of thousands of top and bottom, this giant molecules want distribution through the circulatory system by oral to skin is almost impossible.

The latter does not rely on the spectrum, hyaluronic acid decomposition and synthesis are complex biochemical processes, oral intake and body natural hyaluronic acid final degradation products are carbon dioxide and water. While the basic raw material-glucuronic acid and acetyl Glucosamine — Hyaluronan synthase of alternate connection. The two substances are derived from glucose. Synthetase activity and content is hyaluronic acid yield and low key. So, instead of taking it contains hyaluronic acid of health products, it is better to eat two large white bread — it may have made up of starch and glucose.
