What is the appropriate interval for Rejuran Healer or Aqua Glow Injections, and how often should I use a melasma skin booster?

I am an office worker currently coordinating my schedule to visit the store on the weekend soon to receive a melasma skin booster treatment, a type of regenerative ampoule injection, to resolve the internal dryness that has been a concern for me. I have heard that makeup applies much better and the skin texture becomes clearer after the injection, so I am really looking forward to it.

Due to my work schedule, it is difficult for me to visit the clinic regularly, so I would like to calculate my schedule in advance. I am asking approximately how many weeks or months I should typically schedule a follow-up visit for the next melasma skin booster treatment to continuously maintain this firm and clear skin condition at the cellular level. I am curious about the ideal interval between the first treatment and the next session. I would appreciate it if you could let me know the recommended effective injection interval to maximize the results.
