Hi Debs,
I am pretty sure that you don't need the machine, you will still see great results.... using the machine will increase those results dramatically.
I have a pal who is a massive fan of Environ.. both the product and the company..
She started off without the machine and had a lot of success with her facials.
She holds a couple of 'open days' a year, where Environ bring their face scanner thing (lol you know what I mean!) and they go down very well too.
Now that she is well and truly established with the brand in her area, she will soon be buying the machine with the money she has been putting aside.
Using the machine increases the already great results dramatically, so worth having, but not necessary to get started.
