It depends on how long you have had the piercing. If you have had it for over a year it should stay open for a relatively long time, a completely healed piercing will stay open for weeks maybe even months or years. To prevent the loss of you r piercing though, try not to leave it out of you want to keep it, and wait at least 6 weeks to even change it.
It really depends on the type of piercing and long you've had the piercing.
It depends on how fast your body heals, and how long you have had the piercing. The longer you have had the piercing, the longer it will take to close. This is true for all piercings.
It depends on where it is pierced. The lobes can take about 3 months to completely close up, where your cartilage can take 6 months to even a year to completely close up. It also depends on how long you have had the piercing. A piercing that you've had for years can take years to close (in my personal experience).
It takes as long as it takes once a piercing has healed it depends on haow long you leave the jewellery out, if you are done with the piercing it can take a few days to several weeks for the piercing to actually close once it's a seasoned piercing (seasoned being over a year old).
a septum piercing never closes completly, sorry
if its a fresh piercing the hole will close up pretty quickly, if you've had it for a while the hole will probably take a while to close up
After 3 years chances are good it wont close, the piercing will shrink but not close completely.
It varies, if you have had the piercing for a long time the hole might never close. It does vary, i got my ears pierced over 3 years ago and still close overnight.
The length of time you have the piercing for will be three times that period for the piercing marks to close up and disappear.
It will take as long as your body needs to close the piercing, we don't all heal at the same rate so just leave it alone and it will shrink down and close when it's ready.
It depends on where the piercing is. If it's in your nose then if will take a couple hours to close; if it's in your ear then probably a day or two.
It can be months or years it depends on how old the piercing is and how big the jewellery was, then it depends on your skin type and a few other things, just leave it an carry on with life.
