Cutera Excel V Laser System for Vascular and Pigmented Lesions. Cutera Excel V is a safe and effective technology to treat vascular and pigmented lesions. Many skin conditions manifest in the form of broken or abnormal blood vessels, as is the case of rosacea, in which the facial blood vessels dilate excessively causing redness and flushing. Excel V treats vascular lesions by administering a unique high power green laser, which is absorbed very selectively by the abnormal vessels. This causes the vein walls to collapse and seal shut. Over time the vessels will no longer be visible. Several treatments may be necessary to achieve the desired result. Considered by many as the gold standard for treating vascular and pigmented lesions, the Excel V delivers optimal results, while ensuring the skin is properly protected by a unique cooling mechanism built into the laser.
