Pulsed Dye Laser Vbeam by Candela.

Pulsed Dye Laser PERFECTA by Candela.

These Lasers are 2nd and 3rd generation vascular lasers.

Nd YQG Long Pulse Laser by Candela.

The red blood cell oxyhemoglobin and/or the blood capillary endothelial septum are targeted.

Lasers perform selective photothermolysis, and in doing so enable a great degree of accuracy.

During the laser procedure, a cone of light is emitted very quickly and intensely between 0.15 and 40 ms.

Light is absorbed by the red blood cell oxyhemoglobin of and/or the capilar septum, and is transformed into heat.

This heat remains confined within and around the blood capillary, without being dispersed, and in doing so acts to protect the surrounding tissues.

This leads to vascular rupture and the emergence of a purpura (blue mark), which disappears within a few days.
