I use depilatory creams on my upper lip. I have the odd really strong hair there which I tweeze. If things increase(!) I might consider laser or something.
I epilate legs, armpits and bikini-line. Been doing it for years so no pain. First few times can be bad. I, erm, got a bit drunk, took some painkillers and went for it. I just have the odd fluffy hair under my arms now - barely there - and I epilate that once a week. So easy! And I had dark strong hair under there once....
