Spider veins on the legs: causes and treatment | Eden Aesthetics Clinic

Telangiectasia or Spider veins are skin defects in the form of a “mesh” or “cobweb” that appear as a result of dilation and overflow of small superficial vessels. This phenomenon encompasses not only small veins but also extends its influence to arteries and capillaries. Notable variations in color become apparent: dilated arterioles and capillaries display a red hue that seamlessly integrates with the skin, whereas dilated veins adopt a bluish tint with the potential for discreet protrusions. The most common locations include the face, upper chest, and neck. Thin red lines that appear to extend across areas of the cheeks and nose indicate a spider web-like appearance (rosacea). The reason for the appearance of spider veins on the body is explained by disturbances in the metabolism of sex hormones in the hepatic system. Treatment of spider veins is a very difficult job for a phlebologist.

Most often, patients present with telangiectasis in the legs. In foreign literature, such spider veins are called spider veins. Spider veins on the legs can become quite noticeable, which for some patients creates a cosmetic problem, but they do not hurt. Because of their small size and superficial location, spider veins rarely lead to venous insufficiency, but many seek to eliminate them to improve aesthetic appearance. It is these signs of varicose veins that attract more attention and therefore are most often the reason for contacting a specialist after unsuccessful “treatment” with apple cider vinegar, folk methods, and medications.

How do spider veins bother you?

There is usually no pain, but red or bluish-purple blood vessels appear, usually on the legs or thighs, but sometimes on the face, forearms, or arms. Rarely does the asterisk hurt or cause discomfort and a burning sensation. Sometimes telangiectasis becomes so large and fragile that it begins to bleed.

Causes of spider veins

Why elements of spider veins appear on the body and legs remains a mystery. Sometimes they appear at the initial stage of serious liver diseases. The pathogenesis of the manifestations of spider veins and their causes is precisely unknown. Possible risk factors leading to their formation are:

  • Hormonal problems
  • Taking oral contraceptives.
  • Varicose veins of the saphenous veins (although spider veins often occur regardless of the presence of varicose veins).
  • Heredity.
  • Abuse of hot and spicy foods.
  • Stress.
  • Some medications, especially hormonal drugs, can stimulate the development of spider veins due to increased intradermal blood flow and venous stagnation.

Why are varicose veins dangerous?

The common perception is that spider veins are purely about appearances, dissuading us from donning short attire showcasing these veiny patterns. However, these veins hint at more significant concerns. They might indicate the emergence of varicose veins, possibly fueled by dilated reticular vessels measuring around 2 mm in diameter. Additionally, a delicate network of red or blue vessels could signify chronic venous insufficiency, indicative of poor vein circulation.

Prevention and prognosis

New spider veins on the body arise against the background of hormonal changes and can appear throughout a person’s life, which is why removing spider veins using micro sclerotherapy or laser does not guarantee the appearance of new telangiectasis. The exact reasons why spider veins appear are unknown; the legs have a developed network of intradermal vessels that respond to hormonal characteristics in the body.


Studying the structure of spider veins using a thermal imager. Consultation with a phlebologist is a necessary condition for successful treatment of spider veins. It is important that this is a specialist with significant experience. Diagnosis of spider veins is primarily a diagnosis of the causes of their appearance since the diagnosis can be read on the skin even by non-specialists. First of all, it is necessary to exclude diseases of the liver and female sphere. If stars recur quickly after treatment, it is necessary to examine the level of female sex hormones.

To clarify the connection between spider veins and damage to the main veins, we perform expert ultrasound diagnostics of venous pathology of the lower extremities on all patients. When varicose veins or deep vein lesions are detected, we correct these diseases and then deal with spider veins.


Spider veins require complex treatment: in most cases, it takes place in two stages. The varicose veins feeding the sprocket should be removed first. This is done by sclerotherapy: during the procedure, a special drug, a sclerosant, is injected into the lumen of the vein, which “glues” it together. Thus, it is excluded from the bloodstream, its functions are taken over by other veins. Gradually the sclerotic vessel resolves.

After this, it’s time to remove the asterisk itself, for which doctors at the Phlebology Center use a neodymium laser. Its advantages are the ability to individually select the laser wavelength, as well as the precise, targeted effect of the laser beam on the vessel. The laser has the same effect on the veins as a sclerosant – it glues them together. As a result, small vessels disappear completely, and larger vascular formations, such as hemangiomas, become less noticeable.

For complete or almost complete removal of Spider veins, a course of treatment of 2-4 procedures is required. To make the treatment more effective, as well as to prevent relapses, patients should wear recommended compression stockings after the procedure, which ensures correct pressure on the veins.
