How long does the melasma skin booster treatment take in total?

Lately, my oil-moisture balance has suddenly been off, making my skin texture rough and causing tiny fine lines to appear here and there. It drives me crazy every time I look in the mirror. I decided I couldn't let this continue, so I made up my mind to book an appointment at Maypure this weekend to receive a comprehensive melasma skin booster ampoule injection treatment and a high-frequency soothing procedure.

I have an important business meeting scheduled immediately after my treatment today, so I need to calculate in advance how long I will be staying at the hospital in total.

I would like to know approximately how many minutes the actual melasma skin booster procedure takes, starting from the time spent waiting in the waiting room with the anesthetic cream applied, to the director precisely administering the injections across the entire face. It would be very helpful for me to book the melasma skin booster if you could let me know whether the entire process finishes quickly within about an hour or if the waiting period might be longer. Please also provide the exact duration of the injections themselves.
