Scientists from the Lung and Particle Research Group at Cardiff University in Wales, have reportedly developed a new human tissue lung model that can be used to detect the toxicity of cosmetic aerosol products to humans without testing on animals. Similar models have previously been used in the cosmetics industry, but the new model, which involves cultivating different cells into "micro-lungs," can evidently mimic metabolic processes and allow researchers to detect whether a substance will be harmful after it is broken down in the body.

Kelly BéRubé, Director of the Lung and Particle Research Group, said that using cultures derived from human tissue can produce "robust results" and help researchers avoid using animals for cosmetic research. "We’re now able to predict with very high accuracy what will happen in a human lung," she added. BéRubé also noted that the new lung model allows scientists to "order or pre-screen" subjects and test by gender or pre-existing medical condition, for example. The research team was recently awarded a LUSH Science Prize for innovation in cruelty-free cosmetics.
