What Is Facial Blushing?
Blushing results from an increase in superficial facial blood volume: blood vessels in the skin dilate, and red blood cells color the skin red. The area of skin that can blush is usually restricted to the face, ears, and neck, and in rare cases, the upper body. This dilation of the blood vessels is involuntary. Stress can increase the activity in the autonomic nervous system. Blushing appears to be an involuntary sympathetic nervous system response.
Blushing starts at three years of age. At that age we become aware that others can observe us. Most people, however, do not remember blushing before the age of five. Normally, the intensity and frequency of blushing peaks in teenage years and decreases with age. However, even very old people can blush, and the amount of blushing varies greatly between individuals.

blushing is the result of the capillaries beneath the skin widening. As a conesequence of this more blood accumulates in this area causing the skink to go red

Blushing is vasodilation of the blood vessels of the cheeks.
Common causes are:
* Extremes of emotion
* Rapid changes in temperature
* Hot or spicy foods
* Rosacea
* High fever
* Alcohol abuse or alcohol intolerance
* Medications such as Diabinese (for diabetics) and niacin (for lowering cholesterol -- sometimes contained in high-potency vitamins)
* Menopause ("hot flush" -- due to a drop in estrogen levels)
* Carcinoid syndrome

This is caused by blood coming into the cheeks as the capillaries fill with blood, in response to an emotion like embarrassment.

Being uncomfortable, embarrassed. The blood rushes to the face, making it obvious the person is embarrassed.
Vinny's got my answer beat. LOL. Got so technical on us. :)
