Function and Efficacy of Hyaluronic Acid Harm of Hyaluronic Acid Injection
Hyaluronic acid is the most commonly used product in medical aesthetic plastic surgery. Hyaluronic acid has many beauty functions, such as hydrating and moisturizing, locking skin moisture, beautifying and shaping, changing the shape of five senses and so on. Commonly used for injection beauty.

Function and efficacy of hyaluronic acid

1, water lock

The miracle of deep water directly locking the muscle bottom, the usual daily hydration care is only "superficial effort." When applying moisturizing products, the skin can only absorb a certain degree of moisture. If there is no water locking component, the water will pass after a while and may even take away the original water. Through injection, hyaluronic acid, a water-locking component, is directly replenished to the bottom of the skin, and the excellent water-replenishing and water-locking energy blooms from the source, making the skin foundation better and better, and the external nature is radiant, as smooth and delicate as "shelled eggs" and easy to own!

Step 2 increase moisture

In addition to the penetrating moisturizing effect, applying cosmetics layer by layer will make the skin overwhelmed. Hyaluronic acid, originally a water-locking and moisturizing component in skin, widely exists in skin, connective tissue, mucous tissue and lens, and plays an important role in the dermis of skin. It plays an important role in the overall maintenance and transportation between cells. Extremely nourishing and pure, the skin will fall in love with "drinking water" in an instant, which will be better absorbed by the follow-up care skin care products, and the skin will regain its youthful vitality, relieve dry fatigue and stop being rough and moist.

Step 3 remove wrinkles

Instant wrinkle removal effect, hyaluronic acid can be used to eliminate facial static wrinkles such as head-lifting lines, crow's feet lines and decree lines. Hyaluronic acid is injected into wrinkles or parts that need to be patched, and the three-dimensional tunnel injection technology dedicated to the laser plastic surgery center of the Air Force General Hospital is adopted, which has high technical requirements for doctors. Beauty seekers only feel a little tingling, and the whole process usually takes only 5- 15 minutes, which is very easy. After treatment, the skin can become delicate and smooth, and the facial contour can be carved, giving off a youthful smooth luster!

4. shape; appearance

Natural fillers for facial shaping, injection of hyaluronic acid can also achieve facial shaping and maintain a young face. At present, hyaluronic acid is widely used in facial contour shaping such as non-invasive rhinoplasty, lip augmentation and chin augmentation. The reagent used for injection of hyaluronic acid comes from biological tissues and is a natural component, so there is no foreign body sensation and foreign body residue after injection, no side effects, and the naked eye appearance effect is relatively natural.

Harm of injecting hyaluronic acid

Clinically, hyaluronic acid injection has the following three risks:

Dangerous phenomenon

The first risk is Tindal phenomenon after injection. That is, there is a light blue mark or protrusion at the filling injection site. The reason is that more skin fillers are injected into the thinner parts of the skin, and the layers are shallow. Under the irradiation of light, the original transparent injection material will show a light blue change. Tindal's phenomenon is more likely to occur when injected around the eyes, especially in the lower eyelid and lacrimal groove.

Risk II nodules and bulges

Protrusions on the skin surface or nodules in tissues are mainly caused by excessive injection of fillers. Another reason is cutaneous vascular embolism, which leads to degeneration and necrosis of skin tissue and secondary infection. If it is subcutaneous infection, it is mostly caused by excessive subcutaneous injection, irregular operation or local infection before injection.

Risk of three-vessel embolism

Vascular embolism is the most serious complication of hyaluronic acid injection, which may lead to more serious consequences. Because of the rich blood supply to the head and face and the developed collateral circulation, once it enters the blood vessel, its direction is very uncertain. Vascular embolism is divided into arterial embolism and venous embolism. The manifestation of arterial embolism is local skin whitening, followed by pigmentation; Venous embolism is characterized by local skin color deepening or purple. In addition, in the case of large injection dose, if the injection flows back to the ophthalmic artery branch through the superior orbital artery and the superior trochlear artery, it may lead to blindness or visual field loss, and the incidence of such risks is increasing year by year. For example, after retrograde entry into the common carotid artery through superficial temporal artery, it can then enter the skull, causing serious complications such as hemiplegia and even death due to cerebral artery embolism. Such incidents are occasionally reported. Hyperbaric oxygen therapy can be carried out if conditions permit, and the blind can be transferred to ophthalmology department for treatment. Once vascular embolism occurs, injection should be stopped immediately, and hyaluronidase should be given immediately to improve blood circulation.

Side effects of hyaluronic acid

1, local redness. Local redness is a common phenomenon after rhinoplasty with hyaluronic acid, and physiological redness will disappear within 1-2 days. If it doesn't disappear in 3 days, you should go to the hospital for examination and timely treatment.

2. Local swelling. Hyaluronic acid will cause swelling after rhinoplasty, which will disappear in 1-2 days. If the swelling lasts for a long time, you need to go to the hospital for examination in time.

3. Local congestion. When injecting hyaluronic acid, if the needle touches tiny capillaries, there will be subcutaneous congestion, that is, bruising. In general, the bruising will gradually disappear within 1-2 weeks. Take ACMETEA orally as soon as possible to minimize rejection and side effects and help the skin recover as soon as possible.

4, pigmentation. Generally speaking, pigmentation may occur if the injection is too shallow or if you don't pay attention to sun protection.

5. infection. Infection is rare, which may be due to inadequate disinfection during operation or improper postoperative care. Once an infection occurs, you should go to the hospital for a follow-up visit in time and deal with it as soon as possible.

What is the use of hyaluronic acid?

Hyaluronic acid is an acidic mucopolysaccharide. Human skin will not be tender without it. Of course, the human body itself also contains hyaluronic acid. It has obvious water retention effect and is the strongest moisturizing substance found in the field at present. Hyaluronic acid can be said to be the most ideal natural moisturizing factor. Hyaluronic acid can improve the nutritional metabolism of the skin, make the skin tender and smooth, eliminate wrinkles and increase the elasticity of the skin, so it also has a good anti-aging effect, keeps moisture and is beneficial to the absorption of other nutrients. Therefore, if hyaluronic acid is combined with other nutrients needed by the skin, the absorption effect of other nutrients will be particularly good. At first, hyaluronic acid was only used for moisturizing, but now hyaluronic acid is indispensable in the ranks of plastic surgery and wrinkle removal. Hyaluronic acid for plastic surgery is fermented and cultivated by a certain process, which is relatively stable, so hyaluronic acid can be used to fill wrinkles and enrich some parts, and the effect is immediate. However, this does not mean that the injected hyaluronic acid will not be lost. With the growth of time and age, the water storage capacity of skin will become weaker and weaker, and fine lines and dullness will still appear.
