Hyaluronic acid injection is quite safe to use, and the probability of allergy is very low. Generally speaking, you don't need to do skin allergy test first. However, there are still some complications worthy of our attention, such as arterial embolism, fibrosis and granulation tissue formation, local swelling and pain, local hematoma and even infection, patient anxiety and foreign body sensation.

The probability of these occurrences is not high, but it is still worth discussing with doctors. The best way to avoid complications is to find qualified doctors, good cooperation and postoperative follow-up, slight ice compress, and avoid local collision or hot compress after operation. These are all things to pay attention to. Hyaluronic acid, also known as uronic acid and hyaluronic acid, is a kind of natural polysaccharide and an important component of moisturizing in human skin dermis. Its content will decrease with age, resulting in skin aging due to dryness and lack of water, wrinkles, roughness and uneven skin color.

Hyaluronic acid is a kind of filler, but because it has no side effects, it will be slowly absorbed by the human body, and the retention time is generally as long as 5 years. The nose made of hyaluronic acid is more natural. It is hand-molded after injection and waiting for curing.

As long as you have an injection in a regular hospital, you don't have to worry.
