Found this nice
article on HA augmentation. Same technique as A/G uses, we know the surgeon of course. But the article is nice in that it shows before/after, long term data, covers the complications, etc. This is good stuff, should be on the A/G website. The main item to note from the text is "small volume augmentation". You can see what that means in the example. I think it looks nice there but looks like this surgeon went through the eyes, not the mouth.
