Protect your piercing
An ear piercing takes longer to heal than you may think. To prevent for your piercing from closing follow these guidelines:
Earlobe: For 6 months following the initial 6 week healing period, never leave an earring out of the lobe for more than 24 hours at a time.
Cartilage: For 6 months following the initial 12 week healing period, wear an earring in the piercing at all times. When an earring is removed, immediately replace with another.
