Telangiectasias

Telangiectasias is a skin condition that usually occurs in the face, but can sometimes occur in lower extremities as well. The condition resembles strings and patches of broken veins and capillaries, red and purplish in color, and consists of small, dilated vessels of 0.1 to 1.5 mm in diameter, according to information provided in the article, "Laser Treatment of Acquired and Congenital Vascular Lesions," on eMedicine.com. Laser treatment is an effective solution for visible telangiectasias.
Causes
Telangiectasias is an acquired vascular lesion condition with a variety of causes. Facial telangiectasias, according to the eMedicine article, may occur spontaneously, or can be caused by acne, rosacea, excessive sun exposure, collagen-vascular disease, pregnancy, or alcohol or hormone ingestion. Telangiectasias that occur in children may continue to develop into adulthood. Telangiectasias of lower extremities are more common in women, as they can develop after pregnancy, or due to genetics.
Functions of Laser Treatment
Laser technology is used as a cosmetic correction for skin discoloration and irregularity, such as telangiectasias. Laser treatments vary by type of technology and technique, and the options for treatment are plentiful. The lasers use one or any combination of heat, energy and light beams to target and destroy the abnormal blood vessels, triggering cell repair and new cell growth, as well as collagen production. The skin cells that displayed the redness of the broken veins are replaced with new, healthy cells that contribute to a more even-toned, smoother and younger-looking appearance.
