First of all, don't get wet,
The second taboo.
Third, remember to move the ear patch every day, that is, turn it left and right. It may hurt at first. Just move it gently, and it will turn naturally on the third day (mainly because the tissue grows out)
Fourth, remember that if there is bleeding or pus. Rubbing with alcohol will sting. I always use alcohol because it won't happen, but most people recommend hydrogen peroxide. ) erythromycin ointment is easy to be infected if it is not used well, so it is not recommended. Once a day or once every two days.
Fifth, use silver or gold earrings after one week. It depends. It takes at least a month to get your ears pierced.
