To help reduce flushing, I apply cucumber slices directly to the flushed skin.  I use English cucumbers, peeled and sliced very thin.  The thin slices conform to the skin contours much better than thicker slices.  I apply the cucumber and leave it in place until nearly dry.  Cucumber has a cooling effect that seems to exceed the effect one would expect from moisture alone.  I keep a small container in the refrigerator and take one along when traveling.  I pack a small paring knife in a checked bag when flying.
