I'm pretty sure Avanti hasn't done it with anyone yet so it's fair to say no one in the world has mixed
PMMA and
Ellanse in the penis. I can't find any sources referencing facial injections of
PMMA where
Ellanse is present or vice versa. Avanti doesn't really want to experiment with this seeing as I'm guessing there's basically been no research done. You would think though somewhere in the world someone tried
Ellanse in the face and then
Bellafill or vice versa.
You'll find plenty of examples where people mixed
Bellafill and
HA in the face. Same with
Ellanse and
HA and both appear to be safe.
I'd suggest just seeing how long your gains last and do a few more rounds before considering
PMMA. I'm considering doing this as well at some point but I'm not going to hurry it. I'll gladly wait and let others do it before me. With only the two year version of
Ellanse being available now, it does make you consider it more but even the 2 year version could last 4 years with the collagen lasting longer. A decade from now there could be many guys who have mixed the two and you'll be aware of any ill effect.
Or, a new, better type of filler could come out in which having
PMMA could prevent you from getting it perhaps. Doctors may be willing to inject this filler in the future in to guys who let their
Ellanse dissolve away or are in the process of it dissolving. You'd still be left with collagen for a certain amount of time that would theoretically sustain your gains. Or there could be a reaction that would prevent someone with
PMMA or
Ellanse from getting this new filler and guys with
Ellanse would have to let it be completely gone. Problem, currently I'm not sure there's a good test to determine how many microspheres are left in you. Hopefully some scanning device will be developed that can easily detect microspheres. If a better type of filler does come it in the next decade, hopefully it's safe for guys with
PMMA or
Ellanse to use.
