I got this message from a piercer who is concerned about her clients:
I was wondering what are your thoughts on healing time on navel Piercings? At the shop i work at we have ton of parents with minors getting their navels pierced and plan on swimming at lakes,pools, hot tubs. We try and educate them as much as we can but I feel like it's not getting through to them even college-adults aren't listening to our advice is there any suggestion on what we should do? (we talk to them about it first then hand out the basic care information.
I describe the healing time for navel piercings as 6-9 months. They're likely to have some ups and downs and seem healed off and on within that time, but they can expect to be in an ongoing healing phase for an extended period of time.
