Hi Rachel,
I tried EMLA cream, and that didn't work. I had lidocaine injections, which did work, but they were so painful in themselves, I can hardly recommend it.
You know what worked well enough for me? Ice. Plain old ice. I would hold an ice pack on my upper lip while my electrologist worked on the rest of my face. Then she would ask, "Are you ready for a few?" I would say, "Yeah, go for it", and she would do a few whiskers, usually less than a dozen, and then I would go back to icing down my lip. That way I could get 20-30 hairs on my upper lip per session. It took a couple of years, but I got my whole face cleared like that.
With kindness,
Terri
