False eyelashes are usually made of mink fur, silk or synthetic fibers. We'll look at how each of these types of eyelashes are made, how much they cost, and what are the benefits (and drawbacks) of using each type. Synthetic eyelashes are made with a plastic fiber called PBT or polybutylene terephthalate. This fiber is a type of polyester that is heated and molded into the desired tab shape.
These types of lashes tend to be thicker than normal lashes and generally feel heavier on the eyes due to the stiffer band. Synthetic eyelashes are designed for single use only. Eyelashes are usually made of synthetic fibers, human hair or animal hair. The cheapest, and usually the most popular, option is synthetic, however, they don't usually last that long.
According to the beauty magazine Marie Claire, humans played and beautified their eyelashes in ancient Egypt, although it wasn't until the late 19th century that people discovered that they could lengthen them with human hair. However, false eyelashes were most likely invented as a beauty tool, given that throughout much of history (and to this day) long eyelashes were considered desirable. Although the practice of artificially lengthening eyelashes began in the late 19th century, the first patent for an artificial eyelash was not obtained until 1911.
