Piercing guidelines and time frames for downsizing may vary, people heal at different rates. If you enter your downsize appointment and your piercer best recommends that you wait- it is because the area is still a little "puffy" and some of the initial swelling is yet to dissipate- to downsize these piercings would be problematic and likely lead to further issues including the risk of imbedding- which no one wants! It is still beneficial to come in at this stage so that we can do an in depth check up, worst case scenario is that you are asked to return in a few weeks to try again for said downsize. That being said in most cases we can do the downsize comfortably, Once the piercing is FULLY healed some people choose to go even shorter in their piercing post/bar length or even switch to ring but again this varies per person.
