In addition, there is communication between superficial blood vessels, ophthalmic arteries and intracranial blood vessels in human face. If sodium hyaluronate enters the arteriole for reflux due to improper injection, if it is not treated in time, it may block the ophthalmic artery and cerebrovascular, leading to more serious complications such as blindness, cerebral infarction and even death.
Professor Pingjiang reminded that during the injection of hyaluronic acid, these two common symptoms are worthy of vigilance:
1. Acute pain or abnormal pain occurs during injection, which may be a violent reaction caused by acupuncture to blood vessels;

Main components of hyaluronic acid:
Hyaluronic acid is an acidic mucopolysaccharide, which was first isolated from bovine vitreous by Meyer, an ophthalmologist at Columbia University in the United States, on 1934. Hyaluronic acid, with its unique molecular structure and physical and chemical properties, has many important physiological functions in vivo, such as lubricating joints, regulating the permeability of blood vessel walls, regulating the diffusion and operation of protein, water and electrolytes, and promoting wound healing.
More importantly, hyaluronic acid has a special water retention function and is the best moisturizing substance found in nature at present. HA is known as an ideal natural moisturizing factor, which is widely distributed in all parts of human body. Skin also contains a lot of hyaluronic acid.
The maturation and aging process of human skin also changes with the content and metabolism of hyaluronic acid. Hyaluronic acid can improve the nutritional metabolism of skin, make skin soft, smooth and wrinkle-free, increase elasticity, prevent aging, and is a good transdermal absorption promoter while moisturizing. Combined with other nutrients, it can play an ideal role in promoting nutrient absorption.
