How it Works
The various wavelengths target the anomalous vascular structures deep beneath and selectively irradiate the haemoglobin, thus minimising any interaction with the melanin in the upper layers. Absorption by the haemoglobin and other chromophores changes with the wavelength, generating different effects on the skin and vessels.
The Dye Laser with 595 nm source emission instead offers adequate penetration and oxyhaemoglobin selectivity for treating ectasic lesions at a dermal level (particularly indicated for Port-Wine Stains). Featuring lower absorption, the Nd:YAG laser radiation at 1064 nm allows energy to be transferred even to deeper vessels of greater diameter and different structure (as in telangiectasias of the lower limbs).
Pulsed lights can only be used for treating small-gauge, superficial vascular lesions, especially in patients with pale phototypes. Finally the innovative RightLight™ technology has emission characteristics similar to those of the dye laser but with a much larger treatment surface area of up to 6.3 cm². With this new instrument, it is at last possible to treat superficial vascular lesions, without the annoying problem of purpura.
