For a DC the charge carriers distribute equally all the cross section area of the wire.
But that is not true for an ac signal, when the frecuency increases the center of the cross sectio of the wire is empy of charge carriers, if the frecuency increases, and they concentrate more away the center, that is why Rac increases with frecuency.
