Hyaluronic acid is a kind of hyaluronic acid, also known as uronic acid. Its extraction methods mainly come from animal components, microbial fermentation and chemical synthesis.
Hyaluronic acid can be extracted from connective tissues of vertebrates, such as cockscomb, eyeball, umbilical cord and cartilage. In the past, hyaluronic acid was mostly extracted from animals, but now it is artificially synthesized, which avoids problems such as allergies and infections.
Hyaluronic acid originally exists in the skin, which can help the skin absorb the moisture of the body and the surface layer of the skin, and also enhance the long-term water retention ability of the skin. When hyaluronic acid absorbs water, elastic fibers and collagen are in a moist environment, so the skin is elastic.
Extended data
The role of hyaluronic acid:
1. Maintain skin elasticity. After oral hyaluronic acid absorbs water, the utilization rate of collagen is improved, so the skin is elastic. The role of hyaluronic acid is also reflected.
2, water retention, water locking ability.
The most important function of hyaluronic acid is to keep and lock water. Oral hyaluronic acid can lock a large number of water molecules, which can not only keep the moisture inside the skin, but also capture the moisture in the external environment, keep the skin moist for a long time and enhance the skin's water retention ability.
3. Application of hyaluronic acid in cosmetic medical treatment.
At present, hyaluronic acid has been included in the ranks of wrinkle removal and plastic surgery. This plastic technique is based on non-animal stable hyaluronic acid cultured by bacterial fermentation. Hyaluronic acid is injected into the wrinkles, depressions or parts of the dermis that want to become rich, so as to achieve the effect of removing wrinkles and modifying the face, which can remove wrinkles and change the appearance.
