We recommend waiting 1 year + to have a hoop in any cartilage piercing. Ensure you are fully healed before swapping to a hoop as it can cause bumps.
PIERCING SIZE GUIDE (LABRET & STRAIGHT BARBELL)
If your piercing is fully healed with no bumps or changed angle it will most likely be 6mm. If it has any searring or migrated angle may need a 8mm.
