In which decade were artificial eyelashes made with thin plastic developed?

Artificial eyelashes made with thin plastic were developed in the 1950s, marking a significant advancement in the beauty and cosmetics industry. This era saw a surge in fashion and makeup trends following World War II, triggering innovations in beauty products to meet the growing consumer demand. The introduction of plastic as a material for artificial eyelashes allowed for greater durability, a more natural appearance, and easier application, which contributed to their popularity.

The earlier decades, such as the 1940s, primarily focused on different materials and styles of false eyelashes that were not as refined. As for the subsequent decades, while the 1960s and 1970s did see further innovations and different styles, the initial breakthrough of thin plastic eyelashes specifically occurred during the 1950s.
