The mechanism is involuntary and anxiety may aggravate it, but the facial blush may also occur with or without stress or anxiety. Patients with this condition were born to blush excessively. Physiologic blush occurs more frequently in some individuals than others but generally occurs only in special situations, coming on quickly and fading rapidly. Individuals with facial blush, with or without facial hyperhidrosis, characteristically experience a glowing red face that occurs more frequently than physiologic blush. The blush is intense, constant and lasts for a prolonged period of time.
