Beauty is Skin Deep - the many uses of body fat

Back in July we ran a post about using human fat as a way to fuel an SUV, then there was the Chilean artist Marco Evaristti who served his friends meatballs, cooked with his own body fat.
Now in Lima Peru police said have broken up a gang that has killed dozens of people and sold their fat to buyers who used it to make cosmetics.
We just ran a post about the young Korean singer injecting cooking oils into her face, as some form of skin treatment.
Now this.
Police said they received a tip four months ago about a trade in human fat, which exported the amber liquid to Europe as anti-wrinkle cream.

The suspects allegedly would sever victims' heads, arms and legs, remove organs and suspend torsos from hooks above candles, which warmed the flesh as the fat dripped into tubs below.
Photos of victims remains are see here.
The group stored the fat it collected in used soda and water bottles.
"We have people detained who have declared and stated how they murdered people with the aim being to extract their fat in rudimentary labs and sell it," said Police Commander Angel Toldeo.
The police also want to find the others who bought fat from the gang or are using it.
Remains from some of the victims were found at a rural house in the region of Huanuco where the group worked.
