I'm wondering about the recommended number of laser hair removal sessions for the arms!

As summer arrives and the weather gets warmer, I've been wearing short-sleeved t-shirts and tank tops frequently these days. Since my clothes are getting shorter, I find myself naturally self-conscious about the hair on my arms. Shaving with a razor every time makes my skin sting, and I dislike how it grows back quickly and feels rough, so I am considering getting laser hair removal.

I've heard that you usually need to receive treatments at one-month intervals to see results. How many laser hair removal sessions are typically required to get smooth, clean arms? Since arm hair isn't as thick as hair elsewhere, I'm wondering if it can all be removed in just a few sessions. Also, I'm curious about the pain level of arm laser hair removal compared to other areas. Because the skin is thinner there, I feel like it might be a bit more painful. If anyone has had arm laser hair removal, I would appreciate it if you could share your experience.
