As frequency increases, skin depth decreases. This means most of the current flows at the skin of the material (conductor) (the penetration level is low) hence increasing the skin effect. "Skin effect is the variation of current at the skin of conductor"!

Skin effect is a tendency for alternating current (AC) to flow mostly near the outer surface of an electrical conductor, such as metal wire. The effect becomes more and more apparent as the frequency increases.

It is false.
Because &=1/alpha.
Alpha=root of (w*u*sigma) , as skin effect increases frequency decreases.

Yes, it is true because skin depth decreases as frequency increases not skin effect.
