Gauge is the thickness of the post, while post length and a hoop’s inner diameter determine fit. A 16G piece can fit very differently in a tragus, septum, daith, or navel. Choose hoops by measuring from the piercing hole to the inside edge—not the outside diameter—and choose flat-back studs by post or wearable length. Check the product measurements and ask a professional piercer when unsure.

No. Changing jewelry too early can irritate the piercing, increase swelling, delay healing, or cause the channel to tighten. The exception is a professional downsize or a fit or material issue—have a qualified piercer handle it. Wait until the piercing is fully healed, calm, and pain-free before changing jewelry at home. Healing times vary; general ranges are 2–3 months for lobes, 3–6 months for nostril or septum, 6–12 months for cartilage or navel, and 9–12 months for nipple piercings. These are general ranges, not guarantees.

Wash your hands before handling your jewelry. For a healing piercing, use sterile piercing-safe saline and avoid twisting or over-handling the piece. For loose jewelry, clean gently as directed and dry it thoroughly. Avoid alcohol, hydrogen peroxide, harsh cleaners, perfume, chlorine, and unnecessary soaking. Care needs can vary by material and finish, so follow the product-specific guidance.

For healed piercings, wear depends on the material and finish. Showering and workouts are usually manageable with basic care, but chlorine, salt water, sweat, perfume, and harsh chemicals can affect finishes and irritate piercings. Avoid pools and soaking with a fresh or irritated piercing; rinse and dry jewelry after exposure and follow the product-specific care guidance.

Check the product listing for the closure type. Threadless jewelry uses a pin with spring tension that presses into a hollow post; never straighten, over-bend, twist, or force the pin. Internally threaded jewelry has threading inside the post, so the top screws in and creates a smoother insertion surface. Externally threaded jewelry has threading on the outside of the post, which can drag against or irritate tissue during insertion or removal. Once a piercing is fully healed, you can change the jewelry yourself if you are comfortable and the piece is the correct size and closure type. Do not change an unhealed piercing yourself unless a qualified professional piercer specifically advises it; when a downsize, fit adjustment, or material change is needed during healing, have the piercer handle it.
