Dilated capillaries (telangiectasia) in the face or legs are a common, benign hereditary condition that usually becomes noticeable in the late thirties or early forties. In the face it is common to get visible capillaries on or around the nose and cheeks, and they can appear anywhere on the legs. Sometimes dark patches under the eyes and around the nose are caused by many tiny capillaries showing though the epidermis.

A doctor can treat capillaries with a laser, an electrocautery needle, or by injection of a clotting (sclerosing) agent. All of these techniques cause the blood in the capillaries to clot, stopping blood-flow through them. A variety of different lasers may be used for capillaries, including flashlamp pulsed dye type, neodymium YAG, and erbium YAG.

Injections are the most effective method for the legs, but are usually not used on the face due to possible temporary discoloration and risk of migration of the sclerosing agent. For the face, laser is the most effective procedure, but it is also the most expensive. It is the only technique that can be used on large numbers of tiny capillaries that look like dark patches. 

Electrocautery 

Electrocautery can be used on larger capillaries in the face. Some Net reviewers have said that electrocautery did not work well for them and left a small scar, so it might be prudent to try it on one small capillary first. Often repeat treatments
are required with all of these methods.

Usually you will have to go to a dermatologist or plastic surgeon for these procedures, although in some larger cities there are doctors who specialize in phlebology (treatment of vein diseases). Phlebologists are sometimes listed under "Veins" in the Physician section of the phonebook. Ask your regular doctor who he or she would recommend for these treatments.
