Let’s learn more about the specific situation and what you need to pay attention to when using hyaluronic acid.
1. Risks of hyaluronic acid injection for beauty treatment
Risk - Tyndall phenomenon
Zhang Jinming introduced that the first type of risk is Tyndall phenomenon after injection. That is, light blue marks or bulges appear at the filling injection site. The reason is that more dermal filler is injected into the thinner skin area, and the layer is shallower. Under the irradiation of light, the originally transparent injection material will Shows light blue variation. Tyndall phenomenon is more likely to occur when injecting around the eyes, especially in the lower eyelids and tear troughs.
Risk 2: Nodules and bulges
The appearance of bulges on the skin surface or nodules within the tissue is mainly caused by excessive injection of filler. Another reason is blood vessel embolism in the skin, which leads to degeneration and necrosis of skin tissue and causes secondary infection. If it is a subcutaneous infection, it is mostly caused by too much subcutaneous injection at one time, improper operation, or local infection focus before injection.
Risk of three-vessel embolism
Vascular embolism is the most serious complication of hyaluronic acid injection and may lead to more serious consequences. Zhang Jinming said that due to the rich blood supply and developed collateral circulation of the head and face, once it enters the blood vessel, its direction of travel is highly uncertain. Vascular embolism is divided into arterial embolism and venous embolism. The manifestation of arterial embolism is that the local skin turns white and then appears mottled; the manifestation of venous embolism is that the local skin becomes darker or purplish.
In addition, when the injection dose is large, if the injection flows backward into the ophthalmic artery branches through the supraorbital artery and supratrochlear artery, it may cause blindness or loss of visual field. The incidence of such risks is increasing year by year. . For example, after retrogradely entering the common carotid artery through the superficial temporal artery, it can then enter the brain, causing cerebral artery embolism, leading to serious complications such as hemiplegia or even death. Such incidents have also been occasionally reported. Hyperbaric oxygen therapy can be performed if conditions permit, and those who develop blindness can be transferred to an ophthalmology department for specialist treatment.
Once vascular embolism occurs, the injection should be stopped immediately, and hyaluronidase should be given immediately to dissolve it, improve blood circulation and other symptomatic treatments.
