Long story short: NO
You want the piercing to be as smooth as possible.
You want the tissue to heal around it not into it.
Also the hole cleans itself when it heals, you want those juices to come out, hence the importance of smoothness.
Edit: Speaking from experience. I tried it as a teen… I know, right!
Not the best way to get pus squirting if ya know what I mean…
Oh, it seals up, but the bio-material is generally porous, and the rigid surface irritates the cells. If the object is smooth as butter the healing is much quicker.
Yes, the body gets rid of whatever juices it doesn’t need. However if you insert a foreign object in it that is the least considered normal.
Imagine a splinter. The body wants to encapsulate and eject that, rather then digest it.
If you are interested in piercings I warmly recommend to look up JC’s channel on youtube.
He was doing videos for years about this topic. He covered pretty much whatever could be covered regarding to piercings. google:pangeapiercing
P.S.: If you see him pass my very-best wishes!!
AFAIR there was a snippet about this: if it’s easier to sterilise a polished surface, or how rigid does a surface need to be to prevent growth.
When I was a kid we had iodine-tincture ampules in 1st aid kits.
The alcohol evaporates quickly and as the iodine crystallises it makes the surface hostile for microbes to live on. Same theory goes with photofunctionalization.
We should have started defining bio-bond and bio-safe first.
Luckily this is the off-topic.
However, it would be interesting to start a topic about it.
Back to the practical aspect:
An USB port poking out from the skin: Yes, that would likely to be coated with material that binds with tissue. BUT not the stem that goes trhough the skin, only the anchoring bit.
Now, I’m no expert, but there are a couple of points:
-Transdernals present excellent surfaces for skin dwelling bacteria to bond to (for example S. epidermidis looooves infecting inplants/catheters because it is excellent at forming biofilms which are really difficult to kill
it doesnt so much bond with the body as it “sits” in a “skin pocket” with a bigger inside where the anchor sits and smaller opening - the way the transdermal is attached is through holes in the anchor where the skin can regrow back together, it isnt actually bonded directly - now, these are small, and as you can imagine, quite easy to rip. It would probably need just a tug or snagging on clothing or something to create an ooen wound. And the opening where the transdermal ‘head’ pokes out is an excellent ingress point for all sorts of nasties that could infect that wound. And as the infection is partially hidden hidden in the pocket, any antimicrobial agents (antibiotic creams etc) have a hard time getting to the wound and biofilms are also very resistant to them
Im sorry if i am confusing ts 4 am @Coma has more experience with transdermals so she could probably tell you more
