Diet acne vs External force acne

[Jay S1 0]

I'm all about healing acne internally...

But as we are cleansing and avoiding certain foods that may aggrevate acne, I am also aware that external application does indeed affect our skin.

What I don't understand is that if I am to heal my acne by fixing the internal problems, why is it that external application always do affect my skin?

For example: I eat a big mac, next day I breakout. That would be an internal force. But If I were to apply an oil or some sort, say, jojoba oil (which just broke me out recently yet again), and I'd also breakout aswell.

So I'm susceptible to breaking out from both internal and external forces?

How would this affect others who are not affected by internal forces? Such as someone who lives on big macs but has perfect skin. If he were to apply bacon lard all over his face, would he also not break out?
