Injection wrinkle removal is a medical beauty project, and life beauty salon has no injection qualification. However, some unscrupulous merchants are driven by interests and still set up injection programs without qualification. Moreover, in order to maximize profits, they pass off fake and inferior products as regular products, which brings great physical pain and mental stress to consumers. The CCTV TV platform appeals to everyone to treat injection beauty scientifically and teach you several simple and convenient ways to distinguish between true and false hyaluronic acid: First, look at the packaging. Many fake hyaluronic acid packages are very irregular, Italian, French and of various origins. In fact, there are only three kinds of hyaluronic acid approved by China: one is Evan, the other is Christine, and the other is Yimei. If consumers are not sure about the packaging label, there is another way, that is, landing in the country. Secondly, 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. Finally, according to 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 cannot be pushed out. Hyaluronic acid has a small molecular weight, so the needle used is also very small. There are generally 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, and some unqualified plastic surgeons bring their own injections to beauty salons. One person was injected in a beauty salon, and the temple was swollen after injection. This is Ogilvy's performance. The streets are full of fake hyaluronic acid and collagen. The criminals won the favor of some beauty seekers with low spending power at low prices and were cheated as a result. So it needs good identification. Identification step: Step 1: Squeeze a drop of colloidal substance from the needle tube and put it on white paper. If there is oil penetration and halo diffusion, then this thing is definitely not hyaluronic acid, but definitely silicone oil or paraffin oil. This kind of material is prohibited by law. Step 2: If it is water diffusion, 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 residual molded parts on the glass plate were analyzed. If these residues are all molded components, like "Smoothie" particles piled together, it must be hyaluronic acid. If it is a "hard shell-like opaque scab, it is usually Ogilvy; If it is a soft yellowish soft film, it is usually cellulose. If it is not volatile 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: for the identification of whether the solid component is hyaluronic acid, the enzymatic hydrolysis experiment method can be used. The procedure is: put the solid particles into a container filled with hyaluronidase in a 45-degree constant temperature water bath box, and the solid particles can be degraded in about 2 hours. If it does not degrade, it is definitely not hyaluronic acid.
