If it is safe, it should be comprehensively analyzed from the aspects of surgical materials, instruments and technology. That's what my friend did, and she got a tattoo. It is said that the materials used are imported, but I took a look at the box and imported a hair, which is probably more expensive in smuggled goods. But after tattooing for a month, the brown gradually faded and became a little blue. . . It can be said that any imported goods without production license, inspection by the State Food and Drug Administration and import approval are unsafe! Do you believe what she said? Don't you dare say hello to your face if you don't know where you came from? More importantly, it will stay under the skin for months or even years. The instrument, which also has technical level and unqualified points, has not been specifically studied, but its basic fixed working mode determines that its error is relatively small. Operation, at least this is operation. Although the trauma is not big, it is your face, but who did this operation now? . My little sister who didn't graduate from junior high school trained for a few days without a license in a studio opened by a private teacher (such as my friend) and then did it directly on the guest's face. Do you think it is safe? Of course, there are qualified products and licensed doctors. If you want to do it, you must go to a regular plastic surgery hospital (not Putian Department), otherwise rights protection will become a problem.
