1, early postoperative complications
1) postoperative pain, local redness, itching and ecchymosis. These symptoms usually disappear by themselves within 7 days.
2) Nodules and lumps appear at the injection site. First of all, we must make clear the nature of injection. If it is sodium hyaluronate gel, the hard block will naturally soften in about three days.
3) Itching at the injection site. This may be caused by disinfectant, or the patient may be allergic to injection.
4) pigmentation. This may be caused by poor injection technology and shallow injection.
5) Injection site infection. This usually happens 72 hours or more after operation, and pus spots are formed under the epidermis, which is mostly related to bacterial infection caused by incomplete disinfection before operation or improper care such as makeup and water exposure immediately after operation.
2. Preventive measures for long-term complications
1) overflow. The incidence of lacrimal groove is the highest, because the filling part is shallow, the skin texture is thin, there is some resistance during injection, and local rice-like protrusions are easy to appear due to improper force.
2) Absorption and replacement of injectables. Most of them are in the temporal area, nasal area or buccal area. The frontal and temporal parts are usually injected loosely and horizontally under the superficial temporal fascia. When the injection volume is large, the injection is easy to shift due to gravity, which should be paid attention to.
3) The injection site is periodically red and swollen. The injection site appears red and swollen regularly, every 2 weeks or 1 month 1 time.
4) Chronic granuloma at the injection site. This kind of complication is rare, which has been reported in foreign literature, and there are also cases of pseudocyst formation.
5) Acne or erythema appears at the injection site. It often happens when the injection dose is large, but the injection level is shallow, and the local skin is tight and shiny, and erythema can last for several months.
6) Vascular compression or embolism. Hyaluronic acid injection mostly occurs in eyebrow lines, nasolabial sulcus and nasal tip. Because these parts are rich in blood vessels and have extensive communicating branches with terminal arterioles such as ophthalmic artery and dorsal nasal artery, it is easy to cause direct vascular embolism after injection, which may lead to blindness, nasal tip necrosis and partial upper lip necrosis.
3. Inject hyaluronic acid?
Hyaluronic acid is a skin care method that many female friends compete to choose. But is hyaluronic acid good for skin care? If female friends have dry skin in their lives, you can use some hyaluronic acid. In fact, hyaluronic acid has no direct moisturizing effect, and sometimes it even absorbs a lot of water. Therefore, the skin care effect of hyaluronic acid for external use is generally not good, and the skin care effect of hyaluronic acid injection is good, so you can choose regular hospital injection.
According to research, hyaluronic acid has a good moisturizing effect on human skin. Therefore, many cosmetics and skin care products will use hyaluronic acid. How about hyaluronic acid? Under normal circumstances, the best function of hyaluronic acid stock solution is to moisturize and lock water, and the effect is very remarkable. People's skin generally contains hyaluronic acid, but it will gradually decrease with age. So people's skin will become dull and aging, and many tiny wrinkles will be formed. How about hyaluronic acid? It can be seen that hyaluronic acid also has certain anti-aging effect.
In addition, in order to ensure the effect of hyaluronic acid, we must use the right method. The use method of hyaluronic acid stock solution is as follows: you should open the hyaluronic acid stock solution, and then drop the stock solution between your thumb and forefinger when using it. Next, spread the stock solution evenly on your face with your fingers, and remember to massage for a few minutes to make your face absorb better. The reason why the stock solution falls into the tiger's mouth is because the body temperature there is low, which will not affect the stability of the stock solution. If dripped on the palm, the stock solution will be absorbed by the higher body temperature of the palm.
There are more and more female friends wearing hyaluronic acid skin care. These female friends must pay attention to buying regular hyaluronic acid, otherwise it will do great harm to the body. If there are a series of adverse reactions after playing hyaluronic acid, you need to take corresponding drugs for conditioning treatment. If infected, it is necessary to cooperate with drugs such as Callicarpa nudiflora Capsule for anti-inflammatory treatment, and only in this way can patients be prevented from getting more harm.
