telangiektasi

Telangiectasia refers to the dilation of small blood vessels, resulting in visible, thread-like red or purple lines on the skin. These dilated capillaries are typically harmless but can be a cosmetic concern or a sign of an underlying medical condition. Telangiectases commonly appear on the face, particularly around the nose, cheeks, and chin, as well as on the legs, arms, and other areas prone to sun exposure or trauma.

The exact cause of telangiectasia varies, but several factors contribute to their development. Sun exposure is a primary trigger, as ultraviolet (UV) radiation weakens the walls of blood vessels, leading to dilation. Hormonal changes, such as those occurring during pregnancy or menopause, can also cause blood vessels to enlarge. Chronic alcohol consumption, high blood pressure, and certain medications may further increase the risk. Genetic predisposition and connective tissue disorders, like Ehlers-Danlos syndrome or scleroderma, are additional contributing factors.

Telangiectases are generally painless and do not pose serious health risks unless they are associated with a more severe condition. However, they may indicate an underlying issue in some cases. For example, spider angiomas (a type of telangiectasia) on the face or upper body may signal liver disease, while leg telangiectases can sometimes be linked to venous insufficiency. A healthcare professional can help determine whether further evaluation is necessary.

Treatment options for telangiectasia include sclerotherapy, laser therapy, and intense pulsed light (IPL) treatments. Sclerotherapy involves injecting a solution into the affected vessels to cause them to collapse and fade. Laser therapy uses targeted light to seal the vessels, while IPL delivers controlled pulses of light to reduce their visibility. In some cases, lifestyle changes such as avoiding sun exposure, using sunscreen, and managing underlying conditions may help prevent or minimize the appearance of telangiectases.
