How long after you have your belly button pierced can you change the bar?

Ultimately the longer you leave the original jewellery in the piercing the faster it will heal. Changing the jewellery and messing around with the piercing can prolong the healing period and there exists a danger of damaging the piercing by using low quality jewellery. The average healing time (light heal) is about 6 to 8 weeks, a fully healed navel piercing can take up to 6 months to one year before the piercing is what we call seasoned (toughened and able to handle jewellery changes without problems). When buying jewellery don't purchase junk, yeah I know some of the stuff in the mall looks cool but most of it is low quality junk jewellery. When looking for jewellery always check with you local body piercing studiOS, they always carry good quality materials and let's face it there reputation is riding on what they sell. Ask them who made the jewellery, most studiOS will gladly tell you where or who manufactured it. Check the related links for one quality manufacturer I have used for many years, good stuff.
