Sorry for the delay in responding to you! In case you haven’t tried yet, I had a heck of a time practicing on other body parts. I’m not sure why, I just couldn’t manage to get the probe inserted. Maybe a long history of plucking my face left the follicles “looser”?
Anyway, I don’t think practicing on other body parts is all that necessary. Especially since you have experience with electrolysis. As long as you’re careful, you won’t do much damage to your skin. At worst, a small scab that heals quickly.
And as a general update - my chin/throat is now essentially clear! Once a month or so I treat maybe 2-3 hairs - either stragglers or vellus hairs that are becoming terminal.
Considering I have several years and thousands of dollars of electrolysis and laser hair removal behind me to seemingly no avail, I’m surprised and thrilled to have finished my face in a few months with the one-touch. First time in my life I’ve been able to just forget about facial hair for weeks on end.
