I am glad to have a regular person confirm what we have been saying for years; ‘If you know what you are doing, you would much rather trade off work with someone else, than do slow, inaccurate insertions on your own face.’ Even if one was not worried about poor insertions making pock marks and scars, one would just rather get 4 to 10 hairs per minute, than one hair per minute — to say nothing of the fatigue of trying to balance everything you need to do reverse insertions and attempt to see what you are doing.
On the probe size, you will appreciate this, as the magnification used increases in quality, one can get larger and larger probes into the same follicles. I bet I could drop a 4 in your arm hairs, if I don’t miss my guess. Of course, I would be using a Zeiss operating room surgical stereo microscope with 20 to 40 times life size magnification.
On the probe bend, I have been doing this for decades, and never had any problem with excess treatment energy at the bend. If it is happening, it is not enough of a difference to effect the treatments. Of course, I rest assured there will be those who want us to never use this technique until many peer reviewed studies have been filed by “reliable establishment sources”.
