Well, what an interesting experience.
I went home last night with bristles on my head, face, legs and nether region. I stood at the bathroom mirror, turned on my Emoji and started experimenting.
Legs, easy, right now for the groin. Managed to get half done before it became too much. Then my face around my bottom lip, ouch but tolerable. I made a few runs around my neck and chin but was cautious as my wife is well against me on this area. Again it was tolerable but definitely the heavy dark hairs are well attached. Now for my balding head, Top area was easy as not much up there, then slowly down to my ears. I could only manage 10-15mm all around my head then did the complete sides and back of my neck.
Overall I was surprised the pain did not meet my imagination and will be regularly trying to remove more and more then it will be easier to manage.
I am on the fence at the moment if I will stick with the epilator on my legs or go back to waxing as I still cant get all the hairs out. Might just be finding the right timing and system.
I see now that epilator to the face will be a personal choice and if you have a reasonable pain tolerance, I do recommend trying.
