Inquiry regarding leg and underarm hair removal

Hello. I am a man in my mid-30s considering getting leg and underarm hair removal for the first time. I have been doing home care with a razor, but my skin kept breaking out and I was getting ingrown hairs, so I finally decided to get a professional procedure.

I am curious about the effectiveness of leg laser hair removal and how many sessions are typically required to achieve smooth skin. I would also like to know the level of pain and whether it is possible to resume daily activities or exercise immediately after the procedure. I haven't considered waxing because I think it might be painful, but I am curious which is better between laser and waxing.

Lastly, I would appreciate it if you could let me know whether I need to shave myself before the procedure or if the clinic provides the service. I would also be grateful if those who have experience with leg and underarm hair removal could share their reviews or the costs.
