In 1933, a "permanent" mascara called Lash Lure kills one woman and blinds more than a dozen others. This spurs the passage of the Food, Drug, and Cosmetic Act, which gives the FDA loose oversight to ensure the safety of personal care products.
Then, in 1938, the first waterproof mascara hits the market. Unfortunately, it's mostly made out of turpentine, so early adopters enjoyed itchy, red, injured eyes. Another bonus? It's almost unbearably stinky.
