1, look at the packaging, many fake hyaluronic acid packaging is very informal, some are made in Italy, some are made in France, and the origin is varied. In fact, there are only two kinds of hyaluronic acid approved by China, one is restylane produced in Sweden, and the other is Yimei produced in China. If consumers are not sure about the packaging label, there is another way, which is to log on to the website of the US Food and Drug Administration, inquire about the product batch number, and introduce hyaluronic acid through formal channels.

2, look at the solvent state, hyaluronic acid has a small molecular weight, is water-based, feels very delicate when rubbed, and slowly becomes clean and disappears after rubbing several times; 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.

3, look at the size of the needle, the molecular weight of silicone oil is very large, so its needle is very thick, if the needle is too thin, silicone oil can not be pushed out; Hyaluronic acid has a small molecular weight, so the needle used is also very small.

4, sterile sealed packaging, legal hyaluronic acid, are directly put into the syringe, sealed with sterile packaging, as long as you directly unpack the package before use, and then put on the needle to be punched, you can punch, and it will never be packed separately.
