Even if some of the changes that her body have undergone are attributed to natural growth, not all of them can, and it seems inevitable that an experienced surgeon had a hand in her present appearance. According to expert analyses, it is very likely that Hilary got cosmetic dentistry, lip augmentation and rhinoplasty done. It has also been frequently debated that the 26-year actress has had breast augmentation done as well.
Apparently, silicone implants are responsible for the perfect shape of Hilary’s breasts, which have rather defined edges, a sign of breast implants. Moreover, Hilary apparently went from a 34B cup size to 36C, all of a sudden.
Minor rhinoplasty surgery has also been likely performed on Hilary. Before 2010, Hilary had a bulbous nose with a nostril flare, but in 2010 and ever since, her nose looks more elegant and narrower. It has also been suspected that Hilary may have also had lip augmentation done, but apparently it did not go too well. Hilary apparently looks like she has fish lips now, which could be a result of the use of the wrong amount of filler.
Hilary also had slightly large front teeth, something that she was often criticized for, and apparently she also underwent cosmetic dentistry since her teeth no longer appear as large as they used to do.
What is surprising about Hilary Duff going under the knife is her young age. The primary reason that a majority of celebrities decide to get plastic surgeries done is because they wish to extend their careers in their middle-ages. Perhaps a time will come when Hilary Duff might admit that she had gone under the knife in 2010.
