There is no definitive answer to this question as it depends on a number of factors, including the type of ear piercing, the age and health of the individual, and the healing process. However, there are some general guidelines that can be followed.
If you have had a new ear piercing, it is important to wait at least three weeks before changing or removing the earrings. This gives the piercing time to heal and helps reduce the risk of infection. After this initial period, you can change your earrings as often as you like but should clean them thoroughly before each change.
For children under six years old, it is generally recommended that they keep their earrings in for six months to allow for proper healing. For older children and adults, there is no set timeframe but it is generally advisable to leave earrings in for at least six weeks. If you have any concerns about your piercing or experience any pain or discomfort, please consult your piercer or doctor.
