2. How does laser remove vascular lesions?
- Vascular lesions are relatively common abnormalities of the skin and underlying tissues, more commonly known as birthmarks. By exposing a pigmented or vascular lesion to short pulses of visible light, the temperature in the highly concentrated area of haemoglobin can be raised sharply, enough to damage the vessel wall and shatter. The vessels are then absorbed by the body, making them less visible.
