Laser Treatment is highly effective for removing veins, particularly facial veins, spider veins, and deeper veins on the legs, with a success rate of up to 90%. The laser's wavelength is absorbed by the blood, destroying the vessel which the body then eliminates. Advanced Electrolysis, on the other hand, is ideal for darker skin and smaller superficial veins. It involves the use of a fine probe to apply heat to the unwanted lesion, coagulating the targeted blood vessel and initiating the body's healing process.
