is skin sensitivity to a food indicative of an intolerance to that food?

It could be a sign of an allergy/intolerance showing up. My DS used to get a red rash around his mouth when he ate sweet and sour sauce, he has an allergy to soy. He would also get eczema which stopped once we eliminated wheat from his diet however would flair up on his neck after washing his hair - his shampoo contained wheat.

Could be indicative but not conclusive. I'm allergic to fish and get a rash/redness when I touch it.
