So I originally bought a Remington IPL device. It thinned my facial hairs on my cheeks and neck so it wasn't a waste of money. Around my chin and up to my lips it hasn't kept it thinned there.
So I bought one of the oldest home electrolysis kits on the market. The Clean+Easy Electrolosis machine. It does work! Here's the but......

You need impressively steady hands to use it on yourself. Using a magnifying mirror to work on my own face a bit yesterday (my first time trying it) I did have some success. The trick is to find the hair's pore and push a bit. The needle will slip in. It is however pretty easy to miss the hair's pore and find it placed in one with no current hair growth. Hence the need for extremely steady hands. When you hit the right pore it does work as it should. After about 15 seconds a thick puss colored fluid will be coming out of the pore. This is the reactant of the current and salts forming lye. The hair will almost fall out if you got it by just a touch of the tweezers.
The good:
It actually works, hairs are killed. Takes about 15-30 seconds depending on the current setting.
The bad:
Must have steady hands to guide the needle.
Although the needle is blunt if you push to hard you can draw a bit of blood.
All in all it seems a good deal for cleanup work or if you have ALOT of time to work on yourself. Takes just a 9 volt battery. Seems effective at a low current setting. Not much pain at a low setting. Kind of like a mild sting. Cost less than $40 US.
Might be easier if you had a freind and could work on each other. If you trust them that is lol.
