Hyaluronic acid stock solution is a kind of hyaluronic acid (HYALURONIC ACID, referred to as HA), also known as uronic acid. Natural hyaluronic acid is a polymer polysaccharide. It is a linear polymer polysaccharide composed of glucuronic acid-N-acetate glucosamine as a disaccharide molecular unit. Hyaluronic acid originally existed in the dermal tissue of human skin in a gel form. , responsible for storing moisture and increasing skin volume, making the skin look plump, plump and elastic. However, hyaluronic acid will disappear with age, causing the skin to lose its ability to store water, gradually becoming dull, aging, and forming fine wrinkles.

In 1934 AD, Meyer, a professor of ophthalmology at Columbia University, and others first isolated hyaluronic acid from the vitreous body of bovine eyes and analyzed its structure. Because it is uronic acid extracted from Hyaloid (vitreous body, Greek), it is named Hyaluronic acid. The structure of hyaluronic acid is mainly a polysaccharide composed of disaccharide, N-acetyl-D-glucosamine, and D-glucuronic acid. The average The molecular weight is between 105-107Dalton. Hyaluronic acid can be said to be a moisturizing factor for the skin. It has the ability to absorb 500-1000 times its volume. Compared with collagen molecules, which can only carry 30 times more water, it can be said to be the strongest moisturizing substance in the literature today. In addition to its ability to expand volume after moisturizing, its biological stability, resistance to transfer, and water intolerance also make hyaluronic acid a good choice as a tissue filler. Hyaluronic acid in nature is metabolized very quickly, so in order to be used as a filler between tissues, it must be made into a polymer. Such bonds between molecules not only provide biological durability, but also strengthen the hyaluronic acid. The viscosity (viscosity) and water insolubility (water insolubility). The appearance of hyaluronic acid is a transparent, sticky gel-like substance. Hyaluronic acid is a high-molecular polysaccharide. It is a linear high-molecular polysaccharide composed of glucuronic acid-N-acetate glucosamine as disaccharide molecular units. The average molecular weight is between Between 100,000 and 10 million Daltons, it is originally present in human skin tissue, filling the spaces between cells and collagen fibers.

Function of hyaluronic acid stock solution:

Hyaluronic acid stock solution is the best moisturizing and water-locking ingredient, and the effect is extremely significant. However, with aging, hyaluronic acid is gradually reduced in the skin, so apply this The original solution can help the skin enhance elasticity, maintain moisture, and restore youthfulness.

Originally, hyaluronic acid was only used for moisturizing, but it has been included in the ranks of wrinkle removal and plastic surgery. This plastic surgery technology uses non-animal-stable hyaluronic acid cultured by bacterial fermentation, and uses hyaluronic acid as a filler. The injection is injected into the folds and depressions of the dermis, or areas where plumping is desired, to achieve the effect of removing wrinkles and modifying the face. It can immediately remove wrinkles and change the appearance. Hyaluronic acid originally exists in the dermal tissue of human skin in a gel form. It is responsible for storing water and increasing skin volume, making the skin look plump, plump and elastic. However, hyaluronic acid will disappear with age, causing the skin to lose its ability to store water, gradually becoming dull, aging, and forming fine wrinkles. Thanks to the advancement of biotechnology, hyaluronic acid can be extracted from the connective tissues of vertebrate animals, such as cockscombs, eyeballs, umbilical cords, cartilage and other parts. In the past, hyaluronic acid was mostly extracted from animals, while it was synthesized artificially to eliminate problems such as allergies and infections.
