'' (''OED'') adds that mascara is occasionally used on the eyebrows as well.
The ''OED'' also references ''mascaro'' from works published in the late 19th century. In 1886, the ''Peck & Snyder Catalogue'' advertises, "Mascaro or Water Cosmetique... For darkening the eyebrow and moustaches without greasing them and making them prominent." In 1890, the ''Century Dictionary'' defined mascara as "a kind of paint used for the eyebrows and eyelashes by actors." And in 1894, N. Lynn advises in ''Lynn's Practical Hints for Making-up'', "to darken eyelashes, paint with mascara, or black paint, with a small brush."

Through Egypt's influence, kohl usage persisted in the subsequent Babylonian, Greek and Roman empires. Following the fall of the Roman Empire, kohl fell into disuse on the European continent, where it had been considered solely a cosmetic; conversely, it continued to be widely used in the Middle East for religious purposes.
During the Victorian era, social opinion shifted radically towards the promotion of cosmetics, and women were known to spend a majority of their day occupied with beauty regimens. Great efforts were made to create the illusion of long, dark eyelashes. Attempting this, Victorian women made a type of mascara in their own homes.
They would heat a mixture of ash or lampblack and elderberry juice on a plate and apply the heated mixture to their eyelashes.
The product that people would recognize as mascara today did not develop until the 19th century. A chemist named

In 1933, a woman known on court records as Mrs. Brown consented to have her eyelashes permanently dyed.

Years later in 1957, Rubinstein created a formula that evolved mascara from a hard cake into a lotion-based cream. She packaged the new mascara in a tube to be sold with a brush. For use, the cream was squeezed onto the brush and applied to lashes.] Although still messy, it was a step towards the modern mascara product.
Soon, a grooved rod was patented. This device picked up the same amount of mascara for each use. Then the grooved rod was altered to the brush similar to the ones used today. The change in applicator led mascara to be even easier to use, and its popularity increased.
Mascara is now trending towards multi-functional usage, with many mascaras including lash-boosting serums, botanicals, and pro-vitamin-enriched formulæ. Korean technology is at the forefront of the development, and a number of brands use tubing formulæ to coat the lash.
