There was a large research study from China on
HA filler, published in English this year, and the rate of satisfaction and safety profile was reported as very high. I imagine it is much better than fat injection.
I don't know what stance admin has about linking to research studies though? Even some board sponsors like Dr.
Oates have done research studies. They are available on the clinic website.
I noticed that studies from around 2016 had a lot of focus on dermal fat graft/fat injection, then later AlloDerm, but now it seems
HA is starting to be the preferred method.
Obviously, many people will prefer
PMMA, as it is permanent. AlloDerm and dermal fat graft also has this advantage. The advantage of
PMMA is that it is cheaper and easier as it is injectable.
I think there is need for something new though: something which offer the permanent results of
PMMA, but the safety profile of
HA, and easily able to be removed or dissolved if needed.
