Nearly 70% of all women and 30% of men will develop some type of vascular disorder in their lifetime. The exact cause of facial veins is unknown but the following factors are believed to make a person more prone to developing the condition:

Sun Exposure

Repeated and excessive sun exposure can lead to skin damage of the epidermis which in turn can cause broken capillaries in the face. People with light skin are the most susceptible to developing this condition.

Genetics

If you have varicose veins on your legs or you suffer from other vein problems such as weak vein valves, this is usually caused by a genetic predisposition. If someone in your family suffers from facial veins, then you are likely to develop veins on the face as well.

Aging

As we age the vein walls begin to lose elasticity causing them to dilate which can lead to blood pooling in the veins. Skin also becomes thinner as we get older, making facial veins more prominent.

Hormones

Increased levels of estrogen during pregnancy can weaken the vein walls. The high level of blood that circulates during pregnancy can cause the weakened veins to enlarge, leading to blood collecting in the veins. The enlarged uterus can also play a role in causing facial veins. The pressure on the veins from the uterus can also cause the veins to stretch which can lead to clots in the blood and facial veins.

Trauma or Pressure

People, who have suffered a facial injury such as bruising, can lead to prominent veins on the face. Also, any type of pressure that is put on the veins in the face including frequent sneezing caused by allergies or severe vomiting, can contribute to facial veins.

Rosacea

Rosacea is a skin condition that causes redness and swelling of the face. If you have rosacea you may notice spider veins commonly around your nose, cheeks, chin and forehead. Discussing the causes of your facial vein condition with your skin care specialist, will give you the appropriate advice on which course of treatment will be the most successful in removing your facial veins.
