what causes broken veins on face
Drinking too much can also cause the fine red lines to appear on your face and cheeks. Alcohol is known to cause the blood vessels to dilate but continued drinking can weaken the collagen - the connecting tissue in skin - so the veins stay open, increasing blood flow to the face which causes the thread veins.
Broken capillaries, or blood vessels, can be caused by a number of different reasons, some which may be preventable. The most common cause is damage to the skin from sun exposure and excess dilation from a source of inflammation or irritation such as rosacea acne.
1 Causes â There are several causes of broken capillaries.  Trauma â Any form of trauma or injury to the skin can rupture blood vessels. Examples are wounds, skin surgery or intense cosmetic treatments. Pressure applied on your nose due to glasses can also be a contributing factor.
