If she has modified her face it wasn't on this trip, it's almost impossible logistically speaking. Historically? Maybe. I think her face has changed quite a bit since she started but it's hard to tell. I noticed and posted pictures of this fact some days ago and got told to "touch grass," lol. Now you guys are also noticing.
She uses filters and that makes it hard to pin down. This video in particular is using some underlighting so it might change the perception of the face. There's also the potential that she's using AI-realtime filters through OBS but that's unlikely and somewhat difficult.
As to the stream? It was ok, I think they legitimately look like implants hah, I don't think they would fool most people. It is possible they may look more natural as time goes on. They did a pretty good job overall, it's just that she went so freaking big lol.
This is why Aftyn is so missed, even though there's women out there much more attractive. Those women just don't provide the same great content.
It is what it is. People will be disappointed. It's understandable.
