A spider nevus is a common, benign condition of dilated blood vessels in the skin. A spider nevus can occur in anyone. In 40% of female cases, this skin condition manifests itself during pregnancy. The spider nevus is also common in children.​

A spider nevus is annoying for many people. The spider nevus is also called a "spider head", due to the fanning of fine red vessels around the red button. These vessels are compared to the legs of a spider.


Exactly how a spider nevus arises is unclear. Sometimes the spider nevus arises out of nowhere, sometimes due to sun damage or a spot that has been bumped. The spider nevus is visible through a local dilation of a blood vessel in the skin. It is often unclear why the blood vessel dilates. A spider nevus can sometimes resolve spontaneously, but this is uncommon. Hormonal factors can play a role in the development of a spider nevus. In some cases, spider nevus can be caused by chronic liver disease or autoimmune disease. We speak of a spider nevus when there are only a few veins on the skin. 


At The Hague Clinic we remove spider nevus by means of coagulation. Coagulation is a safe and effective way to remove spider nevus. Spots are touched very precisely without damaging the healthy, surrounding skin.


Coagulation therapy is performed with the 'spot remover'. A subtle device with a pointed electrode. An electrical heat (safe low voltage) develops in this point and the spider nevus is touched with it. With a very fine needle, we apply heat to the skin during coagulation therapy. We heat the spots locally and very precisely. You hardly feel this; you only feel pinpricks. Due to the heating, the proteins in the skin coagulate and crusts form on the spots of the spider nevus. These scabs fall off the skin after an average of a week. Below this, a new, beautiful skin is created. Coagulation treatment of spider nevus is safe, fast and very effective.


A treatment with the spot remover is very targeted and safe. With great precision, spots and warts are touched on while the healthy, surrounding skin is left alone. The treatment is effective, so that most spots have disappeared immediately after the first treatment! 


  • After the treatment, the treated skin may still be red for a few hours.

  • Scabs may also form. These disappear on average within a few days to two weeks.

  • During this period you should be careful about putting on and taking off clothes and drying the skin.

  • Try not to scratch the scabs either. The skin will then heal without scarring.


  • Keep the wounds dry and clean for at least 5 days after the procedure.

  • Avoid the sun for 10-28 days (sun holidays and winter sports).

  • Protect your skin well with at least SPF 30, in sun and rain.

  • It is very important that you do not scratch the skin during the process.

  • Avoid sauna, hot baths and sweating (sports) for 48 hours after the treatment.
