I have always found the issue of working alone interesting
Below is a link to some images
session photos on chest
By far the biggest problem assuming you have an half decent machine - thermolysis means you have a hand free for tweezers - is magnification - i reckon that the following items are essential
a powerful magnifying mirror on a posable arm - an old desk lamp one for example allows for YOGA style positions necessary LOL
a bright halogen desk lamp - that creates a sharp image light
a pair of good reading glasses - I use an old pair of my mothers they allow me to work at around 8 inches from the lens
a hand-held magnifying glass
AND FINALLY A HEAD BAND MAGNIFIER with a selection of magnifying lenses - these are cheap and readily available in DIY and tool stores - mine does 1.2 1.8, 2.5 3.5x
A tray for your tweezers
tweezerman points wide grips are nice and mean you can work easily with both hands as they have a wide round grip
tweezerman slants for most of the time wide grip as the points can do more damage than an incorrectly used needle
