It has been said that a "real man" do not care about his facial appearance in public. Thus, makeups had then became a taboo for men in real life but NOT until this era. These years, there has been a number of men who wear makeups when they perform at TV shows and concerts. But do you actually know that makeups has become more acceptable among men than before? These makeups include mascara, black eyeliner (recently called "guyliner" among men), and black eye shadow.

There are actually some popular male singers and celebrities who popularize the usage of eyeliner among men in real life. They are:

1) Russell Brand (British Comedian, Actor, Radio Presenter)
2) Pete Wentz (Member of the band Fall Out Boy)
3) Johnny Depp (Captain Jack in the movie Pirates of the Caribbean)
4) David Philippe Desrosiers (Bassist and backing vocalist for the band Simple Plan)
5) Billie Joe Armstrong (Vocalist for the band Green Day)
