This is well worth a read:
Growing human skin in a petri dish isn’t the first thing that pops into your mind when you hear the name L’Oréal. Yet the French cosmetics giant, whose other brands include Lancôme, Maybelline New York, Ralph Lauren Fragrances and The Body Shop, also produces gelatinous, dime-sized blobs called EpiSkin.
The company’s researchers use the lab-produced tissue to test the efficacy of ingredients and tolerance of products before they go to market. This is part of a larger, ongoing effort within the scientific community to reduce and replace the use of live rabbits, mice and other laboratory animals in tests and experiments.
