I'm confused by this as well.
Bellafill is itself 20%
PMMA so if their solution is 20%
Bellafill that would mean they're injecting 4%
PMMA, seemingly too low to make much impact. But if it's not
Bellafill then where are they getting the
PMMA? Linnea isn't approved in the US and you can't just go buy
PMMA microspheres. Even if you could you've just created a new
Dermal Filler that, as SO mentions, would need FDA approval. I guess they could trial it like is happening with Otter, but how would they ever make it commercial?
The first listed ingredient is carboxymethylcellulose which makes it sound like they're trying to make their own version of Linnea Safe, which also uses a cellulose carrier. Why someone should get a filler cooked up by a Loria affiliate vs one made by a pharmaceutical company, tested for years, and approved by a regulator is a question I would love to hear them answer.
I genuinely hope everything works out for Otter but for anyone else reading this I would urge extreme caution when considering this clinic/procedure.
