Hi Anacristina,
Ok , so as one of string of people who have treated their own faces, and as someone who answers questions quite a bit here on hairtell, I can give you part of the scoop.
As a DIy’er treating your own face it is very possible to do. You dont have to have a ton of knowledge but a basic idea of the process you are doing and hair follicle anatomy will make your treatment more successful. I’m going to disagree with what is probably the opinion of my friend Beate, and say that thermolysis probably would not be my modality of choice for a beginner. Neither would galvanic, I consider it too slow. I think if you are going to DIY that blend is the most forgiving of error . I do therefore recommend you look for a professional grade machine capable of doing blend.
I think the Apilus line of epilators has enough tools to assist a beginner in hair removal. They all use F-shank needles and I like to use an f4 or f5 . I have yet to meet any electrologist who said they disliked Ballet Needles . I use Sterex mostly these days with good success. Either are available from Texas Electrolysis Supply and their sales girl Jennifer is a delight to deal with. They also carry machines but you would probably be better off looking for adds either on hairtell, or craigslist, kijiji or ebay. I usually find a glut of machines available on kijiji in quebec.
I and others have found it is possible with the right ergonomics to kill hair on the chin, lips, and cheek area with more difficult the further back on the cheeks you go. Doing electrolysis under the jawline seems to present the most challenges, and its much beter if you can get someone else to work that area who can get the insertion angle right.
It’s not cheap. Expect a used apilus to fetch $600-$1000 with no issues. It can be done and it’s possible for a beginner to learn how. It’s not an easy thing too do and ergonomics will make a big deal to your success.
