I prefer to think of it as a property that a clever designer can take advantage
of.
For instance, Copperweld(TM) antenna wire has 97
Skin effect is not an advantage it just is. Reality bites like that.
However, reality must be taken into account when designing.

David,
Skin effect is an AC current phenomenon. DC current is not affected. It
iscaused by the frequency effects where AC resistance = (DC resistance)
(resistance of gauge) (square root of the frequency).
Which says that the higher the frequency the greater the skin effect. That
is why antennas a

Aluminum wire has been used for larger (stranded) power cables for many
decades, and it's given good service. You do have to size it larger
