At present, the stock solution of hyaluronic acid is packed in aseptic vacuum, and it can be stored for 2 years without opening, but it must be used up within 1 month after opening, and the consumption of 1 bottle is exactly 1 month.
Hyaluronic acid:
Hyaluronic acid stock solution is a kind of hyaluronic acid (hyaluronic acid? Acid (HA), also known as uronic acid. Natural hyaluronic acid is a kind of macromolecular polysaccharide, which is a linear macromolecular polysaccharide composed of glucuronic acid -N- glucosamine acetate as disaccharide molecular unit. Hyaluronic acid originally exists in the dermal tissue of human skin in the form of colloid, which is responsible for storing water, increasing skin volume and making skin look full, plump and elastic. However, hyaluronic acid will disappear with age, making the skin lose its water storage capacity, gradually becoming dull, aging and forming fine wrinkles. Hyaluronic acid stock solution is a good moisturizing and water-locking component, and its effect is extremely remarkable. However, with the increase of age, hyaluronic acid in the skin is also decreasing. Applying this stock solution can help the skin to enhance elasticity, keep it moist and rejuvenate.
Function:
Hyaluronic acid was originally used for moisturizing, and now it has been included in the ranks of wrinkle removal and plastic surgery. This plastic surgery is based on non-animal stable hyaluronic acid fermented by bacteria, and hyaluronic acid is injected into wrinkles, depressions or parts of dermis that want to become rich, so as to achieve the effect of wrinkle removal and facial modification, which can immediately remove wrinkles and change appearance. Hyaluronic acid, which originally exists in the dermal tissue of human skin in the form of colloid, is responsible for storing water, increasing skin volume and making skin look full, plump and elastic. However, hyaluronic acid will disappear with age, making the skin lose its water storage capacity, gradually becoming dull, aging and forming fine wrinkles. Thanks to the progress of biotechnology, hyaluronic acid can be extracted from connective tissues of vertebrates, such as cockscomb, eyeball, umbilical cord and cartilage. Hyaluronic acid is mostly extracted from animals, but it is artificially synthesized, avoiding problems such as allergies and infections.
