I had much trouble inserting on the arm to do a test run........the probe is too large for finer hairs. I don't believe you can get any smaller needles for the One Touch which is another reason I bought a used pro machine and a variety of probes.
Does anyone have a good trick or advice for DIY arm work? I'm using a F3 in this area and finding insertions so hard because of the way this area slopes - unlike other area where there's more of a "flat" surface.
I use my arm for practise or testing epilators quite often. It's a bit awkward because you MUST work one handed and stretching isnt always possible, but you'll find you can stretch by placing the lower edge of your insertion hand against the arm and pulling the skin . It definitely becomes easier once your accuracy improves and you learn to insert with your dominant and non dominant hand.Other body areas dont face these challenges. With good accuracy you can insert without any stretching at all.
The Laurier probes are the best but only for Thermolysis. If they are used for blend or galvanic the black insulator gets dissolved very quickly and stay in the follicle as a black dots. Mike, is this insulation bio-compatible?
