Generally, there are five kinds of micro-plastic injection filling materials that are easily confused with hyaluronic acid in the market, including Ogilvy (or IngelFallot), silicone oil, paraffin oil, cellulose and collagen. There is a simple way to identify Ogilvy-some "hyaluronic acid" containing Ogilvy are mostly sold in beauty salons, some unqualified plastic surgeons take them to beauty salons for injection, and another one is injected in beauty salons. The temporal lobe swelled after injection, which is the manifestation of Ogilvy. The streets are full of fake hyaluronic acid and collagen. The criminals won the favor of some low-consumption beauty seekers at low prices and were cheated as a result. Therefore, it is necessary to identify them well.

Steps of identification:

Step 1: Squeeze a drop of colloidal substance from the needle tube and put it on white paper. If there is oil infiltration and diffusion, it is definitely not hyaluronic acid. It must be silicone oil or paraffin oil. This material is prohibited by law.

Step 2: If water permeates and diffuses, it may be hyaluronic acid, Ogilvy (or IngelFallot), cellulose or collagen. At this time, further identification is needed! The identification method is: drop a drop of hyaluronic acid in the palm of your left hand, and then touch it repeatedly with your right hand. After a few minutes, after most of the water evaporates, you can see that there are sandy crystal particles in the remaining residue through finger touch or naked eye observation, and there is nothing else. Then this is cross-linked hyaluronic acid, which can basically be confirmed to be real hyaluronic acid and can be used.

The third identification method: put the extruded product on the flat glass and observe it the next day. As a result, after a night of water volatilization, the remaining molded parts on the glass plate were analyzed. If these residual molding ingredients pile up together like "smoothie" particles, it must be hyaluronic acid. If it is an "opaque crust", it is usually Ogilvy; If it is a soft yellowish soft film, it is usually cellulose. If it is nonvolatile oil, it must be silica gel oil or paraffin oil. If there is nothing left in the end, it is probably non-crosslinked hyaluronic acid!

The fourth identification method: to identify whether the solid component is hyaluronic acid, the enzymatic hydrolysis experiment method can be used. The procedure is: in a 45-degree constant-temperature water bath box, put the solid particles into a container filled with hyaluronidase, which will generally degrade in about 2 hours. If it is not degradable, it is definitely not hyaluronic acid. This is the truth of adding brine to tofu. Everything has its vanquisher! Corresponding enzyme, dissolving corresponding compound)

No one can fool you by the above methods! Identification of cross-linked hyaluronic acid, true and false, you are an expert!
