If your skin is red and you're not a tomato or a beetroot, it's very likely that you are sensitive to salt. I say this because salt sensitivity tends to cause skin-thinning and swollen veins. Then because of the thin skin the veins are effectively nearer to the skin's surface, and their red/purple/blue colour makes the skin appear flushed.
I suggest that you try cutting down on salt and salty food. If you take up my suggestion, your high colour will be reduced and you will feel ever so much better! You will lose some excess weight/fluid retention, lower your blood pressure, reduce your risk of stroke, heart attack, cancer and diabetes, increase your energy and pep up your mental alertness. - "Bring it on!"
