I am 53years old, I get face redness please let me know the answer?

There are several possible answers. Rashes are common in older men. If you are of Irish descent there is a fair chance that you need more vitamin B2 than other people. Get nutritional yeast powder and/or B-100 pills. Vitamin B2 is a water soluble dye that turns urine bright yellow. When the color fades, it's time for another pill. Read some books about nutrition so you know how to eat right.

I suggest vitamins because that is the cheapest test. If that doesn't work then you need to see a doctor to test the rash.
