For everyone who is opposed to fake boobs, it looks like your fears can be eased a little. Maimy didn't have much fat, so the surgeon was only able to inject a small amount into certain targeted areas where Maimy wanted more fullness. Once any swelling goes down, this won't be a dramatic increase or difference. And there is no implant or anything foreign. It's all still Maimy, just reconfigured a tiny bit. Her boobs are all breast tissue and fat, just like boobs are supposed to be.
Now, if she's not happy with the results, then she may decide to get actual implants, but is something for another day.
