Radiation-Based Beauty Products
Radiation-based beauty products were all the rage during the turn of the century, where beauty lovers thought they were using the next scientific breakthrough in anti-aging and skincare. “An ever-flowing Fountain of Youth and Beauty has at last been found in the Energy Rays of Radium!” announced a 1918 advertisement for Radior cosmetics. “When scientists discovered Radium they hardly dreamed they had unearthed a revolutionary ‘Beauty Secret.’ They know it now. Radium Rays vitalize and energize all living tissue.”

Of course, women who used these radium products (which were in everything from toothpaste to lotion) saw a slew of terrible health complications years later.
