Protozoa and Mascara

The beauty industry grosses about $265 billion annually.eyelashes
Most of the testing is done on animals.
In the case of
mascara, beautiful lashes come at the expense of the
animals who are used for test subjects.
Rabbits are
often used which can lead to blindness and death.
New research out of Liverpool suggests
that protozoa
may be the alternative. It is felt that these single celled
organisms have enough genes in
common with humans
to make them good test subjects. Protozoa do not have
a central nervous system
and therefore cannot feel pain.
