let me explain it that way...

first of all luscious lips offers a therapeutical cream which may or may not be tested on animals.

the second thing is that there are many ways to test on animals. general motors produces cars however they were conducting animal tests for years. don't ask me how on earth they did it, this is at least what I read on the german PETA website. I suppose they did not force guinea pigs to drive their cars.
maybe it sounds absurd to ask, if a lip pump device was tested on animals but since animal tests are conducted on the most absurd products on earth and I don't want to use any device, cream or whatever , for which animals had to suffer or to die, I thought it would be a good idea to ask the experts just to be sure and to be able to use the stuff without having a nagging consience or questionmarks in my head:)

that's all.
