Blunt needles are not completely safe

It is worth mentioning that, according to the relevant experimental reality, the 27q blunt needle can puncture the blood vessel with a thrust of about 0.5N, and the 18G blunt puncture the blood vessel with a thrust of about 1N, indicating that the use of the blunt needle is not completely safe and risk-free. This result suggests that clinicians using blunt needles should not blindly penetrate violently if they encounter greater resistance in the tissue.

Not all blunt needles are safe. Different quality blunt needles also have different safety. We must pay attention to the difference and choose the actual operation from deep to shallow to comprehensively consider the volume supplement, not only pay attention to the supplement of the injection site volume. , but also pay attention to the distribution of the volume, the only way to create a young, three-dimensional, natural facial shape, and reduce the complications after injection.
