Well here is something new. .. micro needle rollers  We just started using these at the spa and selling them at the distribution center.     Wow... they give new meaning to the term "no pain, no gain".. ha, ha.  So interesting and we are all seeing the results.  Wonder how our clients will react.   When we use them on ourselves we control the pressure.  We are using the ones with the 540 needles now.  They are much more comfortable.  Would love to hear what is happening out there from other people using the rollers.
