In some cosmetic surgeries, plastics like silicone are added to make the face or other parts of the body appear larger. But where does the plastic go? Does it go under the skin layers, between skin layers, or above them? Do they cover nerve endings (i.e. is there a sense of touch), do they restrict things like blood vessels? If somebody with an implant were to get injured near the area they had stuff injected in, would it show up, or pour out, and would this injury heal itself? Is the consistency of it more liquid, solid, or kind of jello-like?

For the record, I am not interested in these cosmetic surgeries. I’ve always found surgeries that have no medical benefit to be very silly, as it’s an additional risk for no real benefit.

edit: I have been informed that plastic surgery does not necessarily mean actual plastics, and the term has existed before the material was a thing! And apparently, silicone is less common since it is difficult to clean up when it leaks, and saline (mildly salty water, similar in concentration to salt in the blood) is now used instead since it is easily absorbed into the body
