Exotherme™ is a transcutaneous vascular laser, dedicated to spider veins and telangiectasias, up to 2mm of diameter, for a safe, efficient and painless treatment. 

Principle

The principle of the Exotherme™ laser is based on the thermal action of the laser. The transcutaneous irradiation (with a penetration of 1 to 2 mm in the tissue) causes tissue selective absorption by hemeglobin (hemoglobin is the main target of the laser).

The effect of selective photocoagulation is based on two effects:

• Conversion of light energy into heat,
• Coagulation of the vascular wall with collagen denaturation.

Selective photocoagulation does not cause purpura (contrary to photothermolysis).
