This is a TREATMENT machine, not a diagnosis machine. Its 10 functions are:
1. Hydro Dermabrasion (deep cleansing)
2. Oxygen Spray
3. Ultrasound
4. RF Radio Frequency (skin tightening)
5. Cold Hammer
6. BIO / Microcurrent
7. Scrubber
8. Hydro / Water Peel
... etc.
It has a Skin Detection lens (the small clear probe on top). That lens just lets you see the skin magnified on the screen - pores, blackheads, oil. It is NOT a smart skin analyzer that will tell you "dryness 70%, oil 40%" like the big facial analyzer machines with camera.
