Ive a feeling that eventually you will have to be level 3 qualified to be able to use cuticle nippers and anything else that can potentially cut the skin and draw blood.
What about waxing, tweezing etc??
I'm level 2 and was taught to wear gloves whilst doing cuticle work.
I don't think the guidelines are there because the world's gone H&S mad. I guess whilst your a student and using tools then you need to be extra cautious - I don't think accidentally nipping someone means you're a bad therapist either, what if the client sneezes or has a fit? Accidents can happen.
For the record I don't wear them because they're not very comfortable
