It's my understanding that the place that makes Epidermx, for what ever reason, no longer does business with their original supplier...thus they had to change it up a bit. The old formula is no longer available as Epidermx but it's the same as Microdermx which is made by another company and is the exact same as the original Epidermx. The new Epidermx isn't as thick as the old, I have heard some people with very sensitive (tender) skin like the new better as it's a bit less exfoliating...but not me I want all the exfoliating I can get. I use Microdermx or Spa Grade Microdermabrasion. great stuff
