Not totally pain-free but pretty darn good
I used this to numb my upper lip for electrolysis and decided to do my chin too, which isn't awful painful like my lip during treatment but thought I might as well.  I put some on after I washed my face about 2 hours before my appointment, about the amount I would use for putting on my regular moisturizer.  I put another thin coating on at 1 hour and then one a half hour before the appointment.  Not sure if I needed all that or if it does any good after a point, but that is what I did.  Treatment was not pain-free, but was MUCH more bearable than nothing.  I will keep using it, over EMLA, which is so much more expensive and takes a long time to ship.  Not sure if EMLA is better or not, but Dr. Numb is good enough for my 3-4 times a year I go to for electrolysis.  It shipped fast and was exactly as described.
