I've never heard it called the 'skin effect' but so be it  if you like
 the termonology ... so be it.

High energy Magnetics proves the theory. 
Then again...electron flow theory itself has never been proven
..it's all based on cause and effect.   IE:  we did this and it did that

Example: (and a question) When was the last time you saw an 
"A.C. LIGHTNING BOLT" ? .  ha !

Lightning is D.C. and will travel the surface of the tree, usually spiraling
down the tree just under the bark. (Lower resistance path than in the air)
If the spiral is tight enough, enough heat energy builds, boils the sap 
(radiated energy
concentrated inside the coil) and the tree explodes. Otherwise
it just splits the bark in a spiral down the tree with little or no immediate
 damage to the heartwood

I believe only AC current exhibits the skin effect
(traveling on the outside of the conductor).  The
higher the frequency the greater the effect.
