I have occasional face flushing on the cheeks which is so pronounced that it can't be covered by makeup. People are noticing. Someone even asked if I was embarrassed. I don't ordinarily drink but my doctor recommended that I drink a glass of red wine every day. I haven't been able to make myself do that very often. Once or twice a week. I did check that one wine I had drunk a glass of did contain sulfites. Another did not. I am not sure that it is connected with drinking. Should I be concerned.
