In an effort to get the same results without using animal testing- L'Oreal partnered with bioprinting startup Organovo to figure out how to 3D print living, breathing, skin that can be used to test products for toxicity and efficacy.
L'Oreal " started farming derma back in the 1980s. In Lyon, France, it runs lab facilities the size of three Olympic swimming pools, dedicated entirely to growing and analyzing human tissues. About 60 scientists work on site, growing more than 100,000 skin samples annually. That's roughly five square meters of skin per year—or 54 square feet, about the equivalent of one cowhide. Each sample is 0.5 square centimeter in size. The fattest are 1 millimeter thick."
