Dermatologist Lisa Garner M.D. advises waiting at least two weeks before participating in certain activities after having ears pierced, reports Dina Roth Port for Parents magazine. Bacteria in lake and ocean water may irritate newly pierced ears during this time when the new piercing is more prone to infection.
To avoid infection following ear piercing, keep the ears and earrings clean, recommends Port. Rotate the earrings, and slide them back and forth gently on a daily basis so the hole maintains its shape. Leave earrings in place for at least six weeks before changing them for a new pair. Earrings must be worn continuously for at least six months to keep the hole from closing.
