Hyaluronic acid is an important beauty product. The authenticity of its products has attracted the attention of many people. Through this article, I hope to help you understand how to distinguish the true and false products of hyaluronic acid products.
In addition to repairing the skin, hydrating the skin, locking the moisture of the skin, hyaluronic acid can also be used for micro-shaping, acting as a filler on the skin, removing wrinkles, shaping facial shapes (such as rhinoplasty, lip augmentation) and so on.
There are many micro-plastic injection fillers on the market that are easily confused with hyaluronic acid, and generally include: omepridine, silicone oil, paraffin oil, cellulose, collagen, and the like.
There is a simple way to identify omepridine first. Many of the “hyaluronic acid” containing omepridine are sold in beauty salons. Some unqualified plastic surgeons bring them to the beauty salon to inject them, if in a beauty salon. Injected injections, the ankles showed edema after injection, which is the result of containing omepridine. Many fake hyaluronic acid and collagen attract huge customers with low consumption power through low prices, thus gaining huge profits.
The method for identifying hyaluronic acid is as follows
- Squeeze a drop of glued material from the needle tube and place it on white paper. If there is oil dip spread, it proves not to be hyaluronic acid, and it is most likely a substance such as silicone oil or paraffin oil.
- If it is formed by the diffusion of water infiltration, it may prove to be hyaluronic acid, omepridine, cellulose or collagen. So you need in-depth testing!
The test method is as follows:
Take a drop of hyaluronic acid on the left-hand palm, then use your right-hand finger to touch the abdomen repeatedly. After a few minutes, after the water is mostly volatilized, after the finger touch or the naked eye, the remaining residue has sand-like crystal particles. There is no other substance other than this, which proves to be cross-linked hyaluronic acid, and it can be confirmed that it is a true hyaluronic acid.
- Place the extruded product on a flat glass plate and observe the results the next day. After a night of water volatilization, analyze the residual components on the glass plate. If these residual substances are shaped components, like fine sand The same granules, prove hyaluronic acid. If it is an opaque knot similar to human body wound condensation, it is generally considered that omepridine, if it is a layer of soft yellowish soft film, is generally cellulose. If it is non-volatile oil It must be silicone oil or paraffin oil. If there is no residual substance at the end, it is most likely non-crosslinked hyaluronic acid.
- For the test whether the solid component is hyaluronic acid, firstly, in the 45 ° C constant temperature water bath, the solid particles are placed in a container containing hyaluronidase, usually after about 2 hours, solid. The particles can be degraded. If not degraded, it proves not to be hyaluronic acid.
The above four methods can be used to test the authenticity of hyaluronic acid.
