I haven’t tried tons and tons of tweezers, but out of the few that I have tried, Sally Hansen‘s “Raise Some Brows” is definitely my favourite. I have used this for a while, and it has always, always been very easy to use. It has never hurt me, so I hope that is the same in your case! I always hated my eyebrows since they were kind of bushy, but these tweezers saved my life. It is a hero!
