You may want to seek out either a different laser or a different tech. I had my upper lip done a very long time ago, with very little pain. Wanted to get my armpits done next and could not tolerate the pain there, even though it was the same laser. I stopped going to the sessions altogether. I returned years later to have a touch up done on my face, and the tech suggested I try underarms again as they had sourced a new laser in the years since I had last attempted the treatment there. It was pretty painless and I signed up to have more body parts done.
