Beauty Hyaluronic Acid Filling Blunt Needle And Sharp Needle Difference

Sharp needle is more sharp, easier to enter the skin soft tissue, less resistance, less damage to the tissue. Recovery is faster, and it is generally believed that the pinhole has closed after 24 hours. But its disadvantage is that it is easy to puncture or puncture blood vessels. When hyaluronic acid or fat is injected, it is easy to enter the blood vessel through the needle injected into the blood vessel and cause embolism, blood supply disorders cause skin necrosis, even blindness, and enter the cerebrovascular and cause cerebral infarction. Blunt needle is difficult to break through the skin, often need a sharp needle to open the skin, then blunt needle injection, the risk of punctured blood vessels will be significantly lower, combined with some injection techniques, embolism complications will be very low. But blunt for skin damage is larger than sharp needle, recovery time is longer, generally believed to be at least 48 hours.
