Following that success, Henry rapidly moved on to bigger targets.
He laid siege to Revlon over their use of rabbits to test cosmetics for potential eye damage, and exerted enough pressure to persuade them to put $750,000 into the search for alternatives. Having seen the boycott that Revlon had narrowly averted and being afraid of incurring similar wrath, Avon, Bristol-Myers and other major cosmetics corporations soon followed suit. Though it took 10 years for the research to achieve results, it was largely Henry's public and judicious watchdog efforts that brought so many cosmetics corporations to where they now truthfully state their products are not tested on animals. From decades spent working on the side of the weak and oppressed, Henry became efficient at masterminding campaigns.
