When you‘re older it’s no problem to take your starter earrings out after 4 weeks and don’t wear any earrings for a couple of days. So yes, you can put your starter earrings out after 4 weeks, but be sure that you wear other earrings as much as possible. Until you‘re sure that the holes don’t close anymore.
Correspondingly, what happens if you take off your earrings before 6 weeks?
Changing your earrings before the recommended six weeks is likely to irritate your new piercing and expose it to bacteria, leading to pierced ear infections. If you remove your earrings out overnight before six weeks, you also risk your holes closing up, prompting you to go back for another piercing.
