Animal testing has long been used to see if personal care products will hurt you. Unfortunately, in addition to often being hideously cruel (like rubbing stuff in rabbits’ eyes), it hasn’t been effective. Humans react differently to certain products; take aspirin, for example, which works well for most people but is bad for many other mammals. A number of different companies have sworn off animal testing. Now there’s a technological alternative that is cheaper and faster. Maybe that will finally snuff out the practice.
