I have been using it weekly for about a month now and it really does scrub off those dead skin cells. I learn't the hard way to not go over one area too many times as it can leave irritation and a red patch ( but this does go away after a few days). I prefer to use it before bed so the skin has a chance to recover overnight and i'm not walking around with a red face! Rinse your face and slather on a rich moisturier afterwards and your skin will feel fab, as well as feeling so soft after the microdermabrasion. I would recommend to NOT use this on bone dry skin, i've found it to be more effective when using after a shower as the skin is a little softer and its easier for the machine to slough off the dead skin cells.
The only reason i havent given it 5 stars is because i dont think i've used it long enough.. only time will tell if the overall texture of my skin will improve, but i have high hopes !
