Does the portwine stain colour change the level of clearance/success?

Hmmm a few suggestions….have
your PWS treated while you are standing and exercise or add a heating pad to
increase blood flow. We have our patients run up and down the stairs sometimes
to get increased blood flow. I don’t think the cooling is changing the
appearance of the PWS, rather the treatment is flushing the area and it gets
harder to see – mark out the area ahead of time with a white pencil. Then do all the
tricks you need to do to increase blood flow.

You need to see a laser fellowship trained physician.  There is no reason you cant get a full leg treatment or with multiple lasers in tandum to get a better result.  Seek the advice of an expert.  Best, Dr. Emer.
