My rule for makeup is, if you can be sure I'm wearing any, it's too much. (Except for dancing, because you have to pile on the makeup or your face looks like a blank oval.)
I never thought of Jackie Chan as metrosexual ... guess I haven't been paying much attention!
It's one of the reasons Jackie lost some of his martial arts status to people like Jet Li -- sometimes he abandons masculinity in the interest of humor. Contrast that to Shaolin Wooden Men (1976) or even later movies like Gorgeous (1999) where he plays more digified characters and doesn't let himself become the joke.
