The cosmetic surgery industry has taken a bizarre turn with the use of fat from donated dead bodies as filler for various body parts. On Vogue's podcast The Run-Through, editor-in-chief Chloe Malle discussed this trend with actor Dakota Johnson. The procedure, involving injectable alloClae, which uses cadaver fat tissue, gained attention after Johnson's character in her film Materialists was depicted undergoing leg-lengthening surgery.
While Malle expressed enthusiasm for the trend, Johnson found the idea unsettling, questioning the ethics of using someone's dead body. The cadaver fat is sourced from tissue banks that have strict consent requirements, ensuring donors are comfortable with the material's use beyond science and medicine. As of July, more than 2,000 patients had received alloClae injections since May 2025.
The trend's macabre origin has led to creative nicknames like "zombie BBLs" (butt augmentation), with some comparing it to extreme cosmetic surgery depicted in horror films.
