…people judge you by your looks.   “Looks” are partially a general preference for youth/health and partial a cultural agreement about what the appearance of wealth looks like (in other words, 200 years ago a serious pallor meant you were wealthy, then it changed to quite tan, now it’s a touch of color, but nothing too extravagant… that’s cultural, not intrinsic).

Her very light makeup makes her look healthier (removed blemishes, brightened lips/eyes) which is an intrinsic preference.

Complaining that humans judge on the basis of appearance is a waste of time.  We do, that’s the sort of creatures we are.  Everyone knows that we do this, and it’s relatively easy to manipulate the situation to your advantage.
