Side effects and harm of hyaluronic acid
Tingdahl 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.
Nodules and protuberances
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.
Vascular 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.
How to avoid sequelae after injection of hyaluronic acid
Choose a regular medical beauty institution for injection. Hyaluronic acid injection has certain requirements for doctors' skills, which can not be solved simply by sticking a needle into the skin. The depth, location and level of injection are all particular. In some cases, doctors need to massage and knead the injection site after injecting hyaluronic acid, which is not something that untrained doctors can do. If the doctor's injection technology is not in place, it is likely to have side effects, so you must choose a formal medical beauty institution to inject hyaluronic acid.
Confirm whether hyaluronic acid can be injected. Not everyone is suitable for injection of hyaluronic acid. Pregnant or lactating women,/kloc-patients under 0/8 years old, patients with local inflammation or infection, there is a great risk of swelling or bleeding when taking anticoagulant drugs, such as aspirin and non-steroidal anti-inflammatory drugs. You can't hide whether you are allergic to hyaluronic acid and your past medical history from your doctor before injecting hyaluronic acid.
Do a good job of nursing according to the doctor's advice after operation. Postoperative care is also an important part in the whole process of hyaluronic acid injection. Do not take a sauna or forcibly massage the surgical site within one week after operation. Do a good job of sun protection to avoid sunburn. Observe regularly after operation and don't eat irritating food and seafood. Don't think the injection is over. Postoperative nursing is very important for later recovery. If you don't take good care of it, you may have sequelae, and it's too late to regret it.
What should I pay attention to after playing hyaluronic acid?
Pay attention to taboos after playing hyaluronic acid.
After playing hyaluronic acid, the general doctor will tell you to pay attention to taboos. For some spicy, greasy and cold foods, you can't eat them. The taboo time is about two weeks. During this period, we must pay attention to a light diet, otherwise it will easily lead to some unnecessary troubles.
Don't touch the water
The area where hyaluronic acid is used should not be stained with water, otherwise it is likely to be red, swollen or inflamed. You can gently wipe it with a towel at ordinary times.
Avoid touching with your hands.
Frequent touching of the parts where hyaluronic acid is used should be prohibited, which will affect the effect and even lead to deformation.
No hot compress
Some friends will be partially red and swollen after playing hyaluronic acid. At this time, you must not apply hot compress, which will reduce the effect of hyaluronic acid and lead to the accelerated decomposition of drugs. At the same time, you can't ice it.
Smoking and drinking are prohibited.
Alcohol and tobacco also have a certain influence on drugs, so friends who like smoking and drinking must give up.
No make-up
Friends with hyaluronic acid on their faces can't wear makeup for a short time, so as to avoid some chemicals in cosmetics entering the skin and reacting with hyaluronic acid.
