Lipoplasticators are an advanced technology used to perform liposuction/lipoplasty.
Following the Great War, lipoplasticators were only owned by elite organizations and expert scientists. The Institute in the Commonwealth are known to held them, and show surprise at the Capital Wasteland's Horace Pinkerton finding one. It requires a massive amount of skill to use. A lipoplasticator was used in the facial reconstruction of A3-21 in 2277.
Lipoplasticators are mentioned only in Fallout 3.
