Bias towards attractive / beautiful people in derm?

I've been looking at the web pages of derm residency programs, and it seems like the overwhelming majority of the residents are attractive females. Many are downright smoke shows. I'm a bit stunned, honestly. The dudes are more variable in the facial aesthetics department, but it seems like they're all at least lean / not overweight. Are they selecting for good-looking people in derm or am I just seeing things?
