I would like to inquire about laser hair removal.

I am planning to get laser hair removal again, and I am curious about the typical treatment cycle and number of sessions. I would also like to know if the frequency or required number of sessions varies depending on the area. I am wondering how often I should receive treatment for optimal results, and how many sessions are needed to see a noticeable reduction in hair. I am also curious about the level of pain involved. Please let me know if it is just a stinging sensation, and if the pain varies significantly depending on the area. Is the pain particularly severe in sensitive areas like the underarms or Brazilian waxing? I am also wondering if anesthetic cream is used, and if you have any experience, please let me know how long discomfort, such as redness or stinging, lasts after the procedure!
