Laser Vascular Lesion Treatment (Hemangiomas & Spider Veins)

Facial vascular lesions are among the most common cosmetic concerns treated by aesthetic dermatologists. Telangiectasias — small, dilated superficial blood vessels visible as red or purple thread-like marks — commonly appear on the cheeks, nose and chin as a result of rosacea, chronic sun exposure, genetic predisposition or skin conditions that weaken the vessel wall. Haemangiomas are benign proliferations of blood vessel endothelial cells that may be…

Laser treatment of vascular lesions uses the principle of selective photothermolysis targeting haemoglobin: the laser emits a wavelength absorbed strongly by oxyhaemoglobin but weakly by melanin and surrounding tissue. When the vessel wall absorbs the laser energy and converts it to heat, the endothelium is damaged and the vessel coagulates and collapses; it is then gradually reabsorbed by the body's inflammatory clearance process over the following…

MUDr. Helena Závodská delivers the Nd:YAG pulses directly over the visible vessels using the appropriate handpiece configuration for the lesion size and depth. Fine spider veins on the nose or cheeks may clear visibly within two to four weeks of a single session. Larger haemangiomas or more extensive telangiectasia networks typically require two to three sessions for complete resolution. Immediately after treatment the target vessel may appear darker…
