After ear piercing, you need to pay attention to the hygiene of the earlobes, sterilize the earlobes, and reduce the turning of the earrings and squeezing the ear holes. 1. Pay attention to the hygiene of the earlobes: after ear piercing, keep the earlobes as dry and clean as possible within one to two weeks. Avoid contact with dirty water, dirty things, and keep the ear holes dry and ventilated. 2. Pay attention to the sterilization of earlobe piercing: sterilize the earlobes with 75% alcohol 2-3 times a day after the operation, and also take some medicines (such as vitamin C) orally as prescribed by the doctor in order to promote faster healing of the wounds. 3. Reduce the rotation of the earrings and squeeze the ear holes: the earring pins and the pinnae should be fastened relatively loosely, leaving a certain gap to avoid swelling and inflammation, and avoid touching the ear holes with contaminated objects or frequently rotating the earrings. Avoid squeezing the pierced ear when sleeping. If there is any inflammation or infection after ear piercing, you should consult a doctor as soon as possible.
