The unique efficacy of the 1940nm laser stems from a fundamental physical property:
The Three-Step Process：
1.Precision Energy Delivery
â—†The 1940nm laser beam penetrates the skin,and its energy is preferentially and intensely absorbed by the water molecules within and surrounding the wall of the target vein.
2.Direct Vessel Wall Closure
â—†Upon absorption by water,the energy is immediately converted into heat.This heat is not diffused within the blood but is directly and concentratedly applied to the vessel wall itself.
â—† This causes the vessel wall (endothelial cells and supporting tissue)to undergo instantaneous
dehydration,contraction,and coagulative necrosis.This process can be visualized as a “precision photothermal weld”of the vessel wall.
3.Lasting Fibrosis and Absorption
â—† The successfully closed vein transforms into a fibrous strand,which is then naturally
Metabolized and cleared by the body’s own systems over the following weeks and
months,leading to its permanent disappearance.
it corresponds to a peak absorption wavelength for water molecules.This means that when its laser
energy is delivered to biological tissue,it is instantaneously and efficiently absorbed by the water content within the tissue.
