what is hyaluronic acid injection for face？

Hyaluronic Acid (nicknamed HA) is a naturally occurring linear polysaccharide compound whose sugar-based components contain D-glucuronic acid and N-acetylglucosamine. Let me introduce myself below. Hyaluronic acid is widely distributed in the extracellular matrix of connective tissues such as skin, vitreous body, aqueous humor, synovial fluid, and placenta in mammals and humans. It has no race and tissue specificity. Therefore, pure hyaluronic acid is not immunogenic. The content of I in the blood of healthy adults is 10-100 mmol/L, and the average content of I in the serum is 30-44 mg/L.

The physiological properties of hyaluronic acid are determined by the large molecular weight and hydrophilicity of hyaluronic acid. It is the glycosaminoglycan with the largest molecular weight (50,000) and the largest number in the extracellular matrix of the dermis. Due to the negative charge on the surface, the disaccharide unit in hyaluronic acid has very strong hydrophilicity and can bind a large number of water molecules. It has a strong function of retaining water and can maintain a suitable moist environment between cells. It is a natural moisturizing factor. .

Hyaluronic acid in the human body is mainly found in the skin, and the dermis is composed of a matrix composed of collagen and elastin in the extracellular fluid rich in hyaluronic acid. Hyaluronic acid in the skin can help the skin withstand stress and protect the subcutaneous tissue from damage. Hyaluronic acid also has a lubricating effect, allowing the skin to change shape and volume as bones and joints move. The distribution of endogenous hyaluronic acid in the skin and in the body is constantly changing. With age, the reduction of hyaluronic acid and the corresponding reduction in the ability of hyaluronic acid to bind water molecules can lead to reduced skin volume, wrinkles and dry skin.

So what can I do?

1. Facial wrinkle removal

Hyaluronic acid beauty is applied to frown lines (between eyebrows) and crow's feet

Excessive sunken frown lines, when injected with botulinum toxin alone, often cannot get satisfactory results, and when injected with hyaluronic acid, the effect will be even better.

2. Hyaluronic acid beauty applied to the corners of the mouth

Although the lines produced when pouting are dynamic lines, filling the sunken lines with hyaluronic acid will have a good effect.

3. Hyaluronic acid beauty applied to nasolabial folds (nasolabial folds)

Elimination of nasolabial wrinkles is the most commonly used purpose of hyaluronic acid for wrinkle removal. According to the depth of the nose wrinkles and the depth and location of the wrinkles, it generally takes about 2 injections of macromolecules. The injection sites include the depression on the outer nose, the nasolabial folds themselves, and the lower part of the outer side of the lips.

4. Facial plumpness 1. Lip augmentation: Generally speaking, human lips will shrink with age, wrinkles will appear, and the corners of the mouth will also sag due to aging. Hyaluronic acid filling lip augmentation has won certain praise. 2. Abundant forehead: Hyaluronic acid is a polymer polysaccharide with a transparent and viscous gel-like substance. The hyaluronic acid injected in medicine is a purified component. When injected into the forehead, it will interact with the original hyaluronic acid in the body. Fusion, the skin will swell, the forehead will become flat and raised, the safety is extremely high, and the effect is very significant. 3. Filling dents: Hyaluronic acid can also be used to fill some acne scars, trauma, scars caused by surgery, and congenital defects.

5. Although the development of rhinoplasty technology has reached a certain height, since hyaluronic acid injection has been used for rhinoplasty, rhinoplasty such as prosthetic rhinoplasty has been favored due to the advantages of hyaluronic acid rhinoplasty, which is quick to form, does not require surgery, and has no pain. Certain challenges.
