The Groupon deal said the sessions would be 30 minutes in length. When I called to schedule an appt. I asked how long she thought I would be in the office, wait and all. She then told me that the session would be at least 20 min. long. I questioned her about this and pointed out the fact that it is advertised as 30 minute treatments. She said thatt the deal does not include a facial, only the micro derm. I book the appt. I drive 45 minutes to get there and I go in for the micro derm and she took less than 5 minutes on my face! I leave without tipping, I call back to talk to her about the length of the session. She said that it only takes less than 5 minutes to get a micro derm. Wrong!!
