I found this on Restylane, made with hyaluronic acid, which exists in the human body.

Thank you for the link. Well I was thinking not only Hashimotos but other auto immune diseases and our bodies just want to attack any invaders. I mean some fillers are made out of material that we already have in our bodies..I forgot which one..maybe it was Restylane.
When I read again this sentence, I was not happy with how it could be interpreted. "With the incidence of Hashimoto's being what it is, this is probably a very normal outcome." What I intended to portray was that you could find that incidence of Hashi's in almost any group, so it was not at all unusual, and certainly not to be construed as cause and effect.
With Hashi's the thyroid glands are somehow identified as being foreign to the body and the autoimmune system produces antibodies to attack the thyroid glands until they are destroyed. Why this happens has not been scientifically determined.
From personal observation, I think the incidence of injectable fillers or implants is far less than the incidence of Hashimoto's. LOL And of course there is the fact that men also have Hashi's, even though it is a much lower incidence. So it seems doubtful that Hashi's can be positively related to injectable fillers/implants.
I did run across this somewhat limited information.

In this study there two cases of female patients with implants that later developed Hashi's, 11 and 15 years after implants. With the incidence of Hashimoto's being what it is, this is probably a very normal outcome. This is reflected in the statement at the end of the abstract.
"Hashimoto's thyroiditis is recognized as a subset of chronic auto-immune thyroiditis, and its association with SBI is rare. In these 2 observations, an association without relation is possible, but a future survey of similar cases seems warranted."
