EMLA works, if that is the numbing cream being used, IF it is applied properly. It needs to go on thick, like cake frosting (1/4") and it needs to be left on for 1 - 1 1/2 hours, occluded with plastic wrap. A little passive warmth from laying your hand on the site will help absorbption to deeper layers if your hair is coarse and deep.
Everyone, just remember if you read an advertisement or an article about laser hair reduction being comfortable or painless as opposed to electrolysis being very painful, be highly suspicious. My laser failures have all described laser as excruciating pain, unlike the sensation of electrolysis. Electrolysis, when performed by a skilled electrologist with the newer professional epilators hardly comes close to excruciating, if it is performed correctly with high quality tools. Just had to do some contrasting here.
