only insofar as it's parceled with youth

[Maybo]

We're obsessed with appearance but, it seems, only insofar as it's parceled with youth.
(The WORN Archive: A Fashion Journal about the Art, Ideas, & History of What We Wear by Serah-Marie McMahon)

Does "only insofar as" mean "only when"?

I found it means "to the degree that".
But I still don't understand: ".....it seems, only to the degree that it's parceled with youth."

They seem to be saying "We are obsessed with appearance but only when it is associated with young people".
