How does the laser work?
For most spider veins on the legs the laser or intense pulsed light are
probably the best treatments. The treatments are effective because
the wavelength of light that penetrates the skin has a selective affinity
for blood vessels. It passes harmlessly through the top layer of
skin leaving it essentially intact. When it hits the targeted blood
vessel, it causes it to slowly heat up and seal itself. By treating
the vessels with a wider, slower pulse width, the energy has a chance
to slowly accumulate in the blood vessel causing it to seal, but is dissipated
from the skin, allowing it to cool down and prevent any possible scarring.
What should I expect during treatment?
Each pulse feels like someone snapping an elastic band against the skin.
Some patients report feeling nothing at all. Most adults tolerate
this amount of pain very well. For patients with a lower pain threshold,
an anaesthetic cream can be used. Treatments usually last anywhere
from a few minutes to half an hour. Your therapy may take multiple
treatments spaced two to four weeks apart, depending on the number of
blood vessels present and on the depth and size of the vessels.
After treatment there is usually minimal redness that can last a few minutes
to an hour. Rarely, a tiny bruise or crust may result. Patients
are advised to wear support hose for three days after treatment.
Is the intense laser light safe?
Yes, the light is safe. Safety goggles must be worn by the patient
and the laser surgeon during the procedure to protect the eyes from the
bright light.
