Realising that even if this device does actually work, it's not going to be practical to use in the long run. It got delivered to my office on Friday so I rushed home for lunch (yes - I am one of the few lucky people that can do this, don't hate me for it!) and cracked it open.
It's got 3 settings: "off", naturally, "constant wave" and "pulse". The instructions recommend that you treat each area for between 6 and 8 minutes on the "CW" setting, and then follow it up with the same amount of time on "pulse". It was not explained why you should do this. I imagine that the pulse setting is an intermittent burst of more powerful rays than the constant setting, for deeper penetration. Or something.
I have quite a few spots about my person, but the problem is they are spread out over a large area. Meaning due to the size of the device (around 2 inches/5cm in diameter) I could only really treat 1 spot at a time. So I spent my enitre lunch hour (and over-running this by 20 minutes) treating 3 spots. This is sub-optimal.
I expect it's best used when watching the telly (something which I invest far too much time in than I should!) but it's still not really practical when treating areas on my back which I can't see. Also keeping the bloody thing in one place for the whole 12 minutes is proving to be tricky. On a couple of areas now I have found that the device had slid off the spot I was trying to treat, ending up treating a patch of skin that doesn't need it!
I'll stick with it for the time being but I have a funny feeling that I'll subconsciously reconcile my bad skin with being able to do other things in my life. We'll see how it goes.
