[In vitro cell culture technology in cosmetology research]

For ages the humanity has been looking for all kind of active substances, which could be used in improving the health and the appearance of our skin. People try to find out how to protect the skin from harmful, environmental factors. Every year a lot of new natural and synthetic, chemical substances are discovered. All of them potentially could be used as a cosmetic ingredient. In cosmetology research most of new xenobiotics were tested in vivo on animals. Alternative methods to in vivo tests are in vitro tests with skin cell culture system. The aim of this work was to describe two-dimensional and tree-dimensional skin cell cultures. Additionally, in this work we wanted to prove the usefulness of in vitro skin cell cultures in cosmetology research.
