Lets take some of the ingredients. The main ingredient in all cosmetics is oil/grease. Unless it specifically says plant oils ,where does it come from ?

A rendering plant is a collection centre for all kinds of dead animals. Carcasses of every decaying body come from everywhere,including factory farms where disease has decimated herds of swine,cattle and poultry. At the plant, the bodies are all dumped together into a huge cooking pot. After a period of cooking, the bodies are subjected to extreme pressure in order to extract the fat from bones,skins, etc. Old cooking grease thrown out by restaurants is added in the pot. Fat is the final product of the plant.

A majority of this fat is sold for cosmetics, especially to manufacturers of lipstick and eye makeup. Some of the most prestigious cosmetic companies in the country are the chief customers of rendering plants. Anyone looking at the elegant ads portraying glamorous models wearing beautiful makeup would never suspect that it is truly a makeup of the refined, colored and perfumed oil derived from dead dogs, cows or pigs. How much of this abominable blend is ingested into the body from the lips and the pores of the skin?

Keratin is a protein taken from the horns , hooves,feathers, quills and hair of animals, the scales and claws of reptiles, the shells of tortoise,turtle,terrapin, and the feathers, beaks and claws of
