Laser has been used for many years, and many colleagues say it is not very good. I don't advise you to use a laser! Laser is to punch holes in the front and back beams, so as long as the focus is not on, you will wear earrings and stick them back and forth, which is easy to get infected. Sometimes the laser doesn't penetrate, and it will be hit again.

The Second Affiliated Hospital of Kunming Medical University has pierced ears.

Yan' an hospital also has pierced ears, and my colleagues wear them there, which is safe and hygienic.
