The Iridex VariLite system, from the USA, is a complex solution in the field of laser treatment of skin lesions. It is used in the therapy of many diseases, such as vasogenic changes, change in vessels of the lower limbs, mild pigmented lesions, skin lesions, inactive acne vulgaris and the removal of individual hairs.

To close the vessels, the laser emits a beam of energy which passes through the layers of skin to a specific depth and is absorbed selectively by the red blood cells – haemoglobin. The breakdown of red blood cells (selective thermolysis) causes the blood vessels to tighten, which results in them being destroyed. It is then absorbed by the surrounding tissues during the normal metabolic processes.
