The safety testing of cosmetics mainly relies on animal testing, which has been strongly opposed by animal protection organizations. The efficacy testing of cosmetics is generally achieved through in vitro cell tests, but given the complexity of human skin tissue, it is difficult to reflect the real situation. In recent decades, the development of alternative approaches for skin irritation and genotoxicity testing has been a worldwide trend. To better reproduce human biology, our developed ex vivo human skin models are derived from real human skin tissue to obtain the closest test results.
