How many laser hair removal sessions would be best for the upper lip? I'm curious about the recommended number of sessions.

I am considering laser hair removal for my upper lip and am wondering how many sessions are typically required to see results. I would like to know if I can feel the effects after just one session, or if it is a procedure that requires multiple sessions over time. I am also curious about the typical interval between sessions and whether there is significant individual variation. Since prices seem to vary greatly by clinic, I would like to know the cost per session and the approximate rates for packages like 5-session packs. I am also wondering if there are any discomforts after the procedure, such as redness, stinging, or folliculitis. And since it is the upper lip... will laser hair removal be very painful? I wouldn't dare do it if it hurts. If anyone who has actually had upper lip hair removal could share reviews, recommended sessions, and cost ranges, it would be very helpful for my decision.
