Capillaries are a common problem on the face or any part of the body. Capillaries on the face may develop due to sun exposure, sudden hot-cold air changes, alcohol consumption, sensitive skin structure or rosacea disease. They may also develop due to genetic susceptibility, hormonal factors such as pregnancy, various drugs and systemic diseases. The reason for the capillaries in the legs is not known for sure. However, they are more common in women, in those with a genetic predisposition, in fat people, and those working in jobs requiring standing for long periods. They are also seen at an increased frequency during pregnancy and those receiving hormone therapy.
The lasers currently used for capillaries are Nd:YAG, pulsed-dye and KTP lasers. Light systems also known as IPL-BBL are successfully used in capillaries on the skin. It is essential to determine the laser type and appropriate parameters according to the diameter of the vessel being treated. While Nd:YAG laser is preferred for thick and deep vessels, pulsed-dye laser and light systems are preferred for medium depth vessels, and KTP lasers are preferred for very superficial and thin vessels.
The pain during the application can usually be tolerated without anesthesia. However, anesthetic creams can be used in those with a low pain threshold. The number of treatment sessions varies according to the thickness and location of the capillary vessels. One or two sessions are usually enough for thin capillary vessels like spider angiomas, also known as spider nevi, but 4-6 sessions may be required for capillary vessels commonly seen on the face. Some vessels disappear instantly during the application while the color of some darkens and it may take 2-3 weeks for the vessels to disappear. Session intervals are usually 3-4 weeks. Temporary redness is expected in the application area. The redness often regresses in 3-4 hours. Bruising may develop after pulsed-dye laser applications. However, encrustation or wound development is not expected. Epithelizing creams and sunscreen should be used after the application. Capillary vessel treatment with laser and light systems should only be performed by experienced staff. Otherwise, they may leave a scar at high doses. It is important that the application is conducted in winter months. There is a higher risk for scar development after applications conducted on tanned skin.
