DIY electrolysis is pretty difficult and quite risky for your skin actually. Even skilled professionals don't do that. However Seana Richmond had electrolysis hair removal on her face by herself. She could give you some tricks.
It's risky? Perhaps Adrien you could comment on what exactly is risky about doing blend on the face yourself? I've found thermolysis isnt as safe, but I'd be really hard pressed to find anything risky about DIY blend, that is unless you were upping the thermolysis currents way too high.
Pretty much everything under the jaw line is difficult to impossible. There is some hear who have done self treatment on the neck ( Beate) but it's mostly difficult to impossible to get accurate insertions on yourself there.With practice you should be able to SLOWLY kill a few hairs there but the best way, is to have someone else doing it. If you are in electrology school, then trade off with another student! The next best thing to being able to put your eyeballs on the table is use magnification source that CAN look from the angle you need. A really strong table magnification mirror, or a digital video feed from a digital microscope. Ive got a table mirror with a ridiculously close magnification. I seem to do better with it than I did with less flexible mirrors as compared to positioning in the past. Like all things with DIY, working out the ergonomics is the hardest part. Even working on a neck on someone else can be difficult if their neck isnt flexible.
