Skin effectwith Flyback SMPS transformer current?

[Flyback]

Hello,
In a flyback SMPS, the primary current contains a DC component. Can we therefore say that the skin effect has no relevance to the DC part of the primary current? In other words, can we say that the DC component of the flyback transformer primary current will just as easily flow through the centre of the winding conductor as through its outer regions?

Assume the AC voltage has no loss. The loss due to capacitance. We are just talking current not voltage.

Think about flyback in continuous mode, where the DC is a major part of the current and AC is small. (big time continuous)

It is safe to think the DC is traveling through all the copper and the AC is on the outside the wire.

In other areas we often take a complex waveform and break it up into it components.
....90%=DC, 5%=1mhz, 2.5% at 2mhz, 2.5% at 4mhz.
Then tread each "frequency" or "harmonic" as its own thing.
