I’m trying to figure out what exactly is the method of action, is it places with more nerve endings or distance from the heart or what? For example, I’m standing out in 50 degrees weather and my face (uncovered of course) feels fine whereas my ears are freezing. My legs, with just one layer of thin pants feel perfectly fine but my arms require several layers to feel warm. My hands are freezing but my feet are fine. Why is that?

Blood flows differently to different parts of the body, and this can be affected by many things (genetics, general health, age, etc).
Furthermore, your body will try to keep important bits warmer so it will divert bloodflow to your core/head rather than extremities. The logic being you can live if you lose a few fingers, but not if you lose your heart.
Most of your blood is in your core. Your extremities get less blood and they generally have less insulating flesh so they get colder faster. However that’s biologically ok as people don’t have organs in their legs or arms and muscles can operate just fine at a lower temperature.
