Dermatology: Flushed skin is usually harmless, but it can sometimes be a sign of an underlying condition. It's best to see a dermatologist if the flushing: - is becoming more frequent or getting worse, - doesn´t seem to relate to heat, exercise, or emotional responses - occurs alongside other unexplained symptoms, such as diarrhea or a racing heart - is causing significant embarrassment, stress, or anxiety
