I used to work at a salon that used matis, so had a few treatments done. I also bought a 500ml cleanser and toner which I used for a year.
I've had the local rep out (Kathy) and she was very helpful.
But, (theres always a but), I didn't like the range enough to purchase it for my room, it wasn't holistic enough for me.
I enjoyed all the facials I had with matis, and really like the eye treatment.
I didn't really get on with the homecare, and within a week of changing my own personal skin range - after using Matis for a year, my skin improved considerably, someone asked if I was wearing foundation as my skin evened out really nicely.
The other good points about Matis, is that they do lots of body treatments too, so you could add to it. The retail is reasonable too. The training is in Newcastle.
I personally wouldn't stock it but only because it doesn't fit in with my holistic therapies.
