I haven't logged in here in a while, good to see that you went back and are getting things evened out. Initial results look promising but as we learned the first time, you kind of have to just go with the process and accept where you end up.
What you said about advocating more for yourself is critical, and having them speak in English is smart too. My biggest regret from the first round is simply stating what I wanted and leaving it at that. I ended up getting a lot more filler than I actually wanted, but that's partly my fault for not understanding exactly how much they were going to put in and correcting them.
I have some issues as well and need to go back for a touch-up. I'm deciding between
Rejuvall and Avanti, so I am very curious how your results unfold. Best of luck!
