I would like to inquire about the treatment time and pain intensity for a melasma skin booster for office workers.

I am writing to inquire about the treatment time and pain intensity of a melasma skin booster for a busy office worker. Nice to meet you. I am an office worker looking to try beauty treatments using spare time during weekday lunch breaks or right after work, and I am writing to ask about the timetable. For a melasma skin booster treatment that involves injecting into the entire face, how generously should I allow the total treatment time, including the visit, consultation, and topical anesthetic application? Also, given that the treatment involves needle injections, I am curious if the pain intensity is extremely severe. I would like to know if it is painful enough to bring tears to your eyes like Rejuran, or if the pain from this product is relatively bearable. I am writing to ask if it is possible to get the treatment quickly without disrupting my daily work life.
