Medically reviewed by Min Clinic Staff | Updated: January 2026
Blush: Redness of the skin as a result of dilated capillaries, typically over the cheeks or neck. Blushing is an involuntary response of the nervous system that leads to widening of the capillaries in the involved skin. A blush is temporary, and it may be brought on by excitement, exercise, fever, or embarrassment. Also known as flush.
