The Candela ND:Yag is the latest laser technology used to treat spider veins.
The hand-held device produces a 1064 nm wavelength that is almost completely transparent to the skin and is highly absorbed in the blood.
This allows the laser beam to pass through the skin and penetrate the targeted vessels, causing the blood inside the vessel to coagulate and the vessel walls to collapse and seal. These vessels are then dissolved within the body.
