DC vs AC, and the skin effect... any insight?

I've known that AC "changes direction", or "alternates polarity", but I was wondering what that looks like on the electron level. Is it the same physical electrons being pushed back and forth doing the work, like a saw, vs DC which is a steady flow of new electrons doing their work and continuing on their merry way?

If this is so, is this what explains the skin effect in AC? Do these "sawing" electrons drift outward with each "pass"?
