I use my normal epilator.
Years ago, a friend told me that she had been epilating her leg hairs for so long, that she had absolutely smooth legs with no regrowth.
So, I decided that I would start doing this too. After about 10 years, my leg hairs were fewer, finer and weaker. By then I was epilating my armpits also.
Then, when the first beard hairs appeared, I took the plunge and epilated my facial hairs too. Like the armpits, it was painful in the beginning. But I kept reminding myself that I would have less hassles when I am older, especially when I may have to depend on someone else to do it for me.
My moustache is now much finer, and just a slight tickle with the epilator.
I do a maintenance "shave" every fortnight or so. The odd black rogue hairs on my chin get the tweezer treatment. The gray hairs can wait for the epilator.
