It could be done with a professional level machine but without throwing some money at it your only going to get a basic model at best. Even with a machine that works it does take some practice and you'll need to understand what it is that your trying to do. There are some good books out there but reading a book isn't going to make you able. At some point you'll need to start treating and removing hairs and here's where it gets tricky. You could do some damage if you're not very careful and thing is you might not realise it till some time after, it might not necessarily be obvious at the time... Some people who call themselves electrologists don't actually know how to remove hairs properly so be careful who you listen to. If you're in the UK I might be able to help you with a machine. I started off with it and did some DIY myself. It's a sterex machine so a long way from being comfortable for face work as far as I'm concerned There are still people out there using them to torture people. I didn't do any face work with it, just chest and I did cause a couple of scars but no pitting. There's a lot to learn and you'll need some supplies. Needles sharps box, after care, sterile wipes etc etc oh yeah and probably the most important thing. Some good magnification. Mine cost me £1500.00 so brace yourself because all in all it's an expensive endeavour. When and if you do start practising having got all your bits and pieces and information together the legs are are a good place to start. Bear in mind though that the legs are a whole different ball game to the face, they're a good starting point but facial hair is totally different, more energy, deeper and the face is the last place you want to be getting it wrong.... So all in all to re cap

It can be done but it's not gonna be easy, far from it....
