Got a groupon for a $300 procedure for $99! Couldn't resist. I have had this done before, years ago, and was very pleased with the results. Just had it done through this Groupon and so far, so good!
You will have some bruising and red spots where the injections are made, but that should vanish in a few days and you will see how the salt-treatment (or saline, as the medical folks say) works on sealing closed the little spider veins so they disappear. I try to go every few years to keep them in check, because they will continue to show up, here and there, over the years. It is just good body maintenance.
