In fact, there are only two kinds of hyaluronic acid approved by China, one is produced by restylane in Sweden and the other is produced by Yimei. If consumers are not sure about the packaging label, there is another way, that is, log on to the website of the US Food and Drug Administration and check the product batch number. The hyaluronic acid introduced through formal channels is recorded on the website.

Judging from the solvent state, hyaluronic acid has a small molecular weight and is water-based. It feels very delicate when rubbed, and it gradually becomes clean and disappears after several rubs. However, Ogilvy is obviously too large and jelly-like, and it is difficult to disappear quickly after solidification. Silica gel is an oil agent, which feels oily when rubbed.

Judging from the size of the needle, silicone oil has a large molecular weight, so its needle is very thick. If the needle is too thin, silicone oil can't be pushed out. Hyaluronic acid has a small molecular weight, so the needle used is also very small.

Aseptic sealed packaging, legal hyaluronic acid, are directly packed into syringes and packaged in aseptic sealed packaging. Just unpack the package directly before use, put on a needle and punch holes, and it will never be loaded separately.
