Skin Flushing/Blushing

Skin flushing or blushing describes feelings of warmth and rapid reddening of your neck, upper chest, or face. Flushing happens as a result of increased blood flow. Whenever there is more blood flow to an area of skin (such as your cheeks), the blood vessels enlarge to compensate. This enlargement is what gives skin the “flushed” effect. Facial flushing is usually more of a social worry than a medical concern. However, it can be linked to an underlying medical issue, such as Cushing disease or a niacin overdose.
