I can't help, just bumping -- I'm also from the Boston area (North), and looking around for the same thing.
FWIW, A & A Laser Electrolysis and Skin Care Associates (Newtonville) has some excellent reviews on Yelp.
Make sure you subscribe to Groupon and AmazonLocal; I've seen ads for laser/electro places over the months, but I had never been interested until just recently. Time to pay attention!
