The problem one wants to prevent is infection. I would make sure the piercing is well healed and without infection before proceeding with the filler. That would be probably 3-4 weeks.
Hi, since the lip pierecing is through the muscle and the lip augmentation filler is above you can do either first. I do agree with you on letting the lip piercing heal completely (a couple of months) if you choose to do that first before having the lip filler (I prefer uisng Restylane, Restylane Silk or Juvederm). Hope this helps.
You can do fillers either before or after your piercing. Do whichever one that you desire more first. Lip fillers are more easily reversible and it may ultimately slightly alter the position or angle of the piercing, so I would probably do that first. It might be smart to let your lip heal for about a month before you do the piercing. Once the piercing is done, I would advise waiting about 1.5 months before any fillers. At some point in the future, the fillers will ultimately dissipate and you may want to refill them...thus getting fillers after a piercing. All good.
From an aesthetic point of view, I'd suggest doing the fillers first, because they will change the shape of your lips and therefore might alter the type and placement of the labret. Please be sure your lips are completely healed from the dermal fillers before moving on to the piercing. I'd suggest at least two weeks between procedures. Be sure to have your lips augmented by a board-certified dermatologist who has expertise in lip anatomy and aesthetics to ensure best results.
I don't think it matters which when you do first, however you will want to wait a few weeks before you go ahead with the second procedure.
Thank you for your question. I do not think that it will likely make a large difference, but consider what you would like the labret to look like with your lips with and without fillers. If you were to have the labret placed after filler placement, the bar may be a bit longer, and may not cause much of an indentation into your lips. If you were to place the labret before filler placement, the bar may be a bit shorter, so when plumped the labret may indent your lips a bit more. Definitely wait long enough to fully heal from the first procedure before doing the second. Hope this helps.
