Here’s Gemma’s inverted navel surface piercing (the lower of the two) pierced w/1.6mm x 20ish’mm PTFE plastic to allow for the initial weeks swelling. Was later cut down flusher, after healing w/ 1.6mm threaded 4mm balls. The traditional belly button piercing, was not pierced by me. A traditional navel piercing is one of the safest piercings regarding catching it and with regards to healing. Like all surface and microdermal piercings, extra care is required with what will usually be a longer healing process.
