Generally, there will be no fakes in regular big hospitals, but to be on the safe side, you still have to learn to distinguish the authenticity. Every hyaluronic acid product has its own anti-counterfeiting measures, such as telephone verification, code scanning verification and official website verification. If imported hyaluronic acid is allowed to be used in China, it will also be affixed with Chinese detailed instructions and ways to verify its authenticity.
The way to identify the master level is to log on to the website of the State Food and Drug Administration and inquire about the batch number of the product. I once met a customer who made 400 fake phone calls one by one to verify the authenticity of every piece of hyaluronic acid he was about to inject. I think this is a responsible behavior for myself and worth learning. In addition, you must choose a formal medical beauty institution for injections!
