Electrolysis takes months, if not years, and many, many sessions.
Personally, I have had laser hair removal sessions for nearly a year now, and what remains is a few dozen white hairs, which cannot be burnt by laser.
So I will finish with electrolysis. I already had a test session.
I hope to have a clear face by the time I get FFS, next year.
Yes, it takes time, patience, dedication. It hurts.
