Then it seems reasonable to assume that we need to put into our evaluation system the ability to objectively quantify the ability of each machine to control all aspects of the abrasion and repeat the same abrasion, on another occasion, merely by setting up the same parameters on the machine.

In other words, we must require the machine to always deliver the density and speed of crystal particles, that we desire, for the abrasion, regardless of how many new particles are waiting to be used in the crystal supply container or, no matter how full, of waste crysatal and skin debris, the waste system is on the machine, we should always get exactly what we ask for from the machine. Time after time and day after day with no variations in performance, unless we specifically ask for the variance. When we set the parameters for the treatment, that is exactly what we should get.

At first glance this seems like a very daunting task, but believe me, in the years of manufacturing, selling and working with these machines, I have come up with some very inciteful methods of evaluation.

There are three very important areas of machine design that will dictate the ability and performance of all Micro-dermabrsion machines; the motor, waste and control interface; the air, crystal injection and control interface; and the Application Handtool Design.
We will start with the Motor, Waste and Control Interface. How well the machine maintains a consistant Vacuum, based on the setting of the Treatment Pressure Adjustment is determined by this parameter. An improperly designed systm will have a slow climbing vacuum during the stroke of the handset on the tissue peaking at the point of termination of the stroke. The abrasion will become harsher as the stroke becomes longer.
To check this issue remove the Waste device and locate the vacuum for this system. Plug this vacuum port and adjust the Treatment Pressure. If there is a movement on the Vacuum Treatment Gauge the machine will not perform in a linear manner over the time of stroke of the Handtool on the tissue. With longer strokes vacuum will rise and there could be capillary damage toward the end of the stroke. Therefore the method of handtool application to the tissue with this machine will be "stroke and lift", as longer strokes will be too high a pressure on the client. This is a poorly designed machine.

Air, Crystal Injection and Control Interface. This area of design will determine the ability of the machine to maintain a constant density of crystal in the air stream which translates into consistent abrasion over time. We will quantify this parameter as well as the Application Handtool Design parameter with objective abrasion pattern evaluation much as we would evaluate a shotgun choke pattern on a target.

We will now move on to evaluating the actual pattern and relate these patterns back to possible design deficiencies in the machine design or in the Application Handtool. We will use a dark picture in an offset printed magazine to evaluate the abrasion of the Micro-dermabrasion Machine. We will change the different parameters of the machine and see what happens to the abrasion picture.
