A needle of hyaluronic acid can sell for 10,000 yuan in a beauty salon, and the cost of fake hyaluronic acid may be tens to 100 yuan. The huge profits can be imagined.
Beauty seekers can distinguish fake hyaluronic acid by the following two methods.
First, the website query code
After getting the medicine, enter the security code on the box in official website, the security code inquiry center of China. The query result of counterfeit drugs is "No such product, please beware of counterfeiting";
In the "China Item Coding Center", the query result of counterfeit commodity bar code information in China is "No goods can be found for the time being", while the query result of foreign barcode information is "No relevant records for the time being".

Second, the physical identification
1. Squeeze a drop of colloidal substance from the needle tube and put it on white paper.
If there is oil leakage and halo diffusion, it is silica gel oil or paraffin oil, which is forbidden by law.
2. If water permeates and diffuses, it may be hyaluronic acid, cellulose or collagen.
For further identification, put a drop of hyaluronic acid in the palm of your left hand and touch it repeatedly with your right finger. After a few minutes, after the water evaporates, there are sand-like crystal particles left, without other impurities. Then this is crosslinked hyaluronic acid, which can be used.
3. Further identification: In a 45-degree constant-temperature water bath box, put the remaining solid particles into a container filled with hyaluronidase, and the solid particles can be degraded in about 2 hours.
If it does not degrade, it is definitely not hyaluronic acid.
