Step 1: Squeeze a drop of the gel-like substance from the syringe onto white paper. If an oily halo spreads, the substance is definitely not hyaluronic acid—it must be silicone oil, paraffin oil, or similar substances. Such materials are explicitly prohibited by law.
Step 2: If a water-like halo forms, the substance may be hyaluronic acid, Omegon (or Ingelfer), cellulose, or collagen.Further identification is required at this stage! The identification method is as follows: Place a drop of hyaluronic acid on the left palm. Using the fingertip of the right index finger, repeatedly touch the substance. After several minutes, once most of the moisture has evaporated, assess the residue through tactile sensation or visual inspection. If sand-like crystalline particles are present and nothing else, this indicates cross-linked hyaluronic acid. It can be confirmed as genuine hyaluronic acid and is safe for use.
Third identification method: Place the squeezed product on a flat glass plate and observe the next day.After overnight evaporation, analyze the residual structured components on the glass plate. If the residue forms distinct, "ice-like" granular clusters, it is hyaluronic acid. If it appears as opaque, "pot-sticker-like" crusts, it is typically Omedin. If it forms a soft, pale yellow film, it is usually cellulose.
Fourth Identification Method: To determine if solid particles are hyaluronic acid, employ an enzymatic hydrolysis test. Procedure: Place solid particles in a container with hyaluronidase solution within a 45°C water bath. Typically, the particles degrade within approximately two hours. If no degradation occurs, the substance is definitely not hyaluronic acid.
