Bill Cosby Nose Pigmentation

Just saw Bill Cosby on Leno’s show, and his nose appears to be a different color than the rest of his face. Does anybody know what causes this?

No jokes, okay? I’m genuinely curious, I’m not trying to be funny or disrespectful.
.

Maybe too much of the rap music? With all the hippin’ and the hoppin, and the bippin’ and the boppin…

Seriously, maybe early stages of vitiligo?

His pigmentation is fading in general…his nose just seems to be going a little faster.

Band name!

Lots of people’s noses are a different shade from the rest of their face. I’ve assumed it’s because most people put more sunscreen on their nose than the rest of their face.
Of course, Mr. Cosby might have just had a bad makeup day.

Yeah, but doesn’t stage makeup usually cover something like that? Link to video.

Good heavens! That’s a terrible makeup job. I dropped “Bill Cosby 2009” into google images search, and it appears he doesn’t look that bad all the time.
