The tiny red blood vessels often seen in fair skins and particularly on the cheeks and at the sides of the nose are often incorrectly called broken capillaries.
They are, in fact, overgrown capillaries and are caused by repeated damage to the skin (such as blowing your nose), a single damage episode (such as squeezing a spot), or from hereditary, lifestyle or medical factors such as UV exposure, high blood pressure or rosacea.
Dilated capillaries can be made worse by triggers such as spicy foods, extremes of temperature, smoking and alcohol consumption.
Sometimes they can have a central spot with little capillaries radiating out from the centre, these are known as spider naevi.
Cherry Angiomas (blood spots) and Milia can be effectively treated with the same procedure.
