a salon I worked at used it, I've had a few facials with the products (nice), even bought the products to use at home (did nothing for my skin) which lasted about a year, cos I got 500ml bottles. Within a week of using Liz Earle my skin was transformed and got compliments from a therapist that worked at the salon!
I took over from a therapist that had the Matis stock in and had an opportunity to buy the whole range for a really good price, I got the rep in to discuss it, but knew that I couldn't promote the range whole heartedly because I didn't believe it could do what it said.
they are a good company, the products are nice enough, the retail is reasonable, but I am looking at a range from an entirely different viewpoint probably, I want products to be as natural as possible, wheras matis have a repuation for performance.
incidentally, the salon has last month changed their matis range for another company, and thats after using matis for nigh on 10 years.
