Hi:
Half an hour with Emla will help, but an hour is better.
You have to put it on thick enough too and use the plastic wrap.
Try some type of pain killer too if you can ahead of time.
If it is too painful let them know. Sometimes they can turn the setting down a bit and still be effective. Some areas are also more sensitive.
My electrolygist uses a Silhouette Tone machine which is not the newest model, but it seems to be working. She often adjusts the settings depending on my tolerance.
Some days I am more sensitive than others.
I go tonight for hours 75 & 76 on my face. Before that I had 9 laser sessions with the Lightsheer.
Good luck with the pain relief.
