The permatweeze won’t work - don’t waste your time trying.
One Touch:
wash face
Sterilize needle & tweezer (the tweezers that come with the One Touch are useless)ends in alcohol & use alcohol wipes on your face
you will need one tsp salt to one cup water
connect machine to 9v battery & turn dial to where you want it (I use no 4 setting on upper lip, 6 on chin)
Insert needle into hair follicle & use slide button to slide needle so it is in contact with hair base (the needles bend very easily - I have given up with the slide button & now use the needle without the pen tip)
wet one finger and place it on the metal stylet/pen touch plate - this should complete the circuit and a loud whining/beeping noise should be heard
lye will weep from the follicle
count 15 seconds and remove wet finger from touch plate before removing needle
the hair should slide out without resistance, do not tug - if it does not slide out, repeat above (instructions say don’t do more than twice)
treated hairs have a sort of clear jelly looking substance around the root
clean treated area with alchohol wipe
apply witch hazel or tea tree oil
disconnect battery between treatments
the main problem I have found with the treatment, apart from the huge needle, is that the connection of the needle in the holder is poor, and it often needs pushing back in
new needles are available on ebay
(you would be much better having professional electrolysis)
