Are there specific standards for the recommended number of sessions or treatment intervals for chin fillers?

I received chin filler treatment at Maypure two months ago. I had a severe receding chin, so my mouth always looked like it was sticking out, but now that a little volume has been added to the tip of my chin, my profile line has become completely sophisticated, and I really enjoy taking selfies these days.

It feels really good that everyone around me compliments me, asking if I've lost weight and saying I look prettier. However, as I can see the product being absorbed little by little over time, I keep getting the urge to maintain this pretty shape for the rest of my life.

I am wondering if there are any established medical standards regarding the recommended cumulative frequency of filler retouches, which are administered periodically to fix and maintain the shape for a long time. I am concerned that getting injections too frequently might cause my jawline to spread out or look unnatural, so I would really like to hear advice from anyone who is knowledgeable about the appropriate number of sessions or intervals for safely continuing filler treatments.
