Hahahaha! They do, i think, and they wear makeup, not only powder, but eyeliner and even eye shadows. They are in the entertainment business after all they have to look their best. I've heard from youtubers that even Korean men (not in the entertainment business) wear makeup, I think they meant powder for their faces. But I have no other sources or experiences..
From a western perspective, it seems outrageous men would have eyeshadows and eyeliner, but then you remember those punk and rock bands that do wear makeup, and you realize that western men do it, but in a different way. So, we are all the same, but different, if you understand what I mean?
