I travel a lot, and have had laser on three continents... Thankfully at this point, it doesn't hurt very much because there aren't that many hairs left. But boy, that first one, yes the upper lip and chin with the highest density, was mindboggling. I always beg for and receive the lidocane cream or similar, left on for a good solid half hour before I let them touch me. Then, on the sensitive areas, I insist they do it pulse by pulse, with a good two second gap betwixt... I could never take the pace of the auto-zap around the mouth. But I'm as clear as anyone after about 10-12 treatments over a year and a half (a good 1500-2000 USD investment all up). Being on HRT and post SRS, I'm not getting new follicles so the laser is also effectively permanent.
