I would like to say the pain gets less -- I kept hoping the reduction in hair would make it so! -- but that has not been my own experience. I've had six sessions now and any pain reduction due to fewer hairs absorbing the laser has seemed to be offset by the increase in laser dosage each time. They just got me up to maximum dose on my last session, so maybe now I can hope for this 'fewer hairs = less pain' effect to kick in (the technician seems to think it might, but we shall see). If anything, the individual pulses in sensitive areas (top lip especially ;_;) were more painful than ever last time.
I haven't tried the numbing cream. I do take painkillers about an hour before I go (if I remember), but I find them pretty limited in what they can do. The pulses themselves are too sharp and intense a pain for everyday painkillers to mask. Maybe they help a little in the immediate aftermath, but it's hard to say. That aloe vera gel though... so soothing... she always applies some of that straight after she zaps me.
It's only 15 minutes of discomfort for a huge and (hopefully) lasting benefit, so I can deal with it, but boy does it make my eyes water... 😮
