Approximately how long does a body laser hair removal treatment take during the summer?

Since I wear sleeveless tops and shorts often this summer, I’ve become really self-conscious about hair removal. Shaving with a razor every time irritates my skin and seems to cause ingrown hairs, so I’m planning to take this opportunity to try laser hair removal at Maypure. I really want to avoid ingrown hairs. I’m planning to stop by briefly on my way home from work on a weekday; approximately how long should I allow for the entire laser hair removal treatment? I am curious if the actual laser hair removal procedure, excluding waiting time, takes only a few minutes. For those who have had laser hair removal on their arms or legs, please advise on the pain level and recommended treatment intervals!
