When you picture ancient Egyptian beauties such as Queen Nefertiti or Cleopatra, they’re probably wearing dramatic black eyeliner. Ancient Egyptians believed that eye makeup1 had properties bestowed2 by the gods that protected the wearers from illness. Modern scientists determined3 that the makeup contains often-harmful lead, so they discounted any beneficial effects. But according to research published in the journal Analytical4 Chemistry, the eye makeup may indeed have prevented disease.

 

Scientists analyzed5 52 different samples from ancient Egyptian makeup found at the Louvre. They identified four different lead-based substances, two of which were man-made, not natural. They then applied6 the substances to a culture of human cells. And the cells experienced a 240 percent increase in the production of nitric oxide7, which is known to jump start the immune system.

 

The ancient marshy8 Nile would have hosted many eye disease–causing bacteria. Application of the makeup may have revved9 up cells’ immunity10 and protected against infection. The chemical compounds were no doubt used initially11 based on appearance. But then wearers noticed they weren’t getting eye infections. The gods got praised, but it was ancient chemists who deserved the credit.
