1, urticaria, dermatosis and itching happen occasionally, so we should stop taking drugs and deal with them properly.

2. Sometimes there will be pain and swelling, which will hinder the infiltration of water, and occasionally there will be edema, redness, heat sensation and local pressure.

As we all know, it is precisely because a substance called "hyaluronic acid" is excessively distributed on Sha Pigou's skin that so many wrinkles are produced. The excess of hyaluronic acid is probably caused by the overactivation of a gene called "hyaluronic acid synthase 2".

When the synthase gene is over-activated, the human body will produce corresponding enzymes to decompose and destroy the redundant parts, which will play a certain role of "self-regulation". Hyaluronidase can dissolve excess hyaluronic acid, thus eliminating side effects.

Extended data:

Hyaluronic acid is a disaccharide unit composed of D- glucuronic acid and N- acetylglucosamine, also known as uronic acid and hyaluronic acid. Its basic structure is a large polysaccharide composed of two disaccharide units, D- glucuronic acid and N- acetylglucosamine. Unlike other mucopolysaccharides, it does not contain sulfur. Hyaluronic acid molecules can carry more than 500 times of water, which is recognized as the best moisturizing ingredient today and widely used in skin care products and cosmetics.

Matters needing attention

1, hyaluronic acid should be handled aseptically, only 1 can be used, and it is forbidden to use hyaluronic acid gel after it is damaged.

2. It is not advisable to inject when the joint inflammation is obvious, and then inject hyaluronic acid gel after the inflammation is eliminated.

3, joint effusion, puncture and drainage of hyaluronic acid gel as appropriate will cause pain outside the joint cavity, so it must be injected into the joint cavity.

4, sometimes it will cause pain. After injection of hyaluronic acid gel, it will be quietly treated locally.

5. Hyaluronic acid will precipitate when it encounters disinfectants such as benzalkonium chloride and seasonal salt. , so pay full attention when using it.

6. Pregnant women and lactating women should use it with caution, those with impaired liver function should use it with caution, and those who are allergic to hyaluronic acid gel should use it with caution.
