I’m a woman. We don’t do it for ourselves, we do it so outward society as a whole doesn’t call us “tired” all day. If I thought I could go into work with no makeup and not get looks or comments, I would.
And while I have my disagreement from Peterson, you’ve completely missed the point to what he said. Makeup emulates the changes a face goes through when aroused. It is tied to attraction, which is tied to sex. It’s not a difficult concept to grasp.
