The absorption of pulsed light in oxyhemoglobin, de-oxyhemoglobin, and the resultant thermal action inside the blood vessels result in intraluminal coagulation, vasoconstriction, and damage to the vessel endothelial lining, all of which contribute to the degeneration and disappearance of any visible vessels.
 

“The vascular component, comprised of small to medium sized broken blood vessels, typically associated with sun-damaged skin can be effectively treated. It is obvious to see that immediately following the treatment the vessels are gone.”
