what causes my face to be real red sometimes and then real pale sometimes?
Redness or paleness of the face is a result of the superficial blood flow in the skin of the face. When dilated, these blood vessels allow more blood to flow through and this creates a redness.Dilation may occur due to heat (thermoregulation), emotion, inflammation or linked to certain toxins within the system that affect these vessels.
