If the capillary dilation occurs on the face and is just formed, it may be a vasodilatory reaction caused by facial dermatitis or facial inflammation. At this time, you can use saline cold compresses to effectively shrink the capillaries and reduce the inflammatory reaction, and also take oral anti-inflammatory drugs, such as temporary oral prednisone, and oral antihistamine drugs, such as levocetirizine hydrochloride. If the capillary dilatation is longer and forms a kind of capillary dilatation, it can be treated by physical methods, such as laser, generally using fractional laser.
