What Causes A Flush Red Face And Neck Area?

I am a 29 yo male, and everyday I experience a flush red face and neck area. I have no known allergies, weigh 190, 5'11", and no medical history. In generally cool climates my symptoms subside mostly, or right when I get up in the morning, but very cold climates trigger flushing as well as the normal triggers for rosacea do; such as spicy foods, exercise, hot weather, alcohol, etc. I have taken noritate from my derm but it seems to calm my skin for a few minutes right when i apply it, then after a few minutes the redness returns. Please help.
