Inquiry regarding filler treatment to improve prominent cheekbones and sunken cheeks

As I get older and lose weight in my face, the areas on both sides of my cheeks look particularly hollow and sunken. As I lost weight in my cheeks, my side cheekbones looked relatively too prominent, and My facial contours have become uneven, so every time I look in the mirror, I look sharp and like someone who has gone through a lot of hardship, which is causing me a lot of stress. People around me recommended getting fillers, saying that sunken areas are immediately filled in and the facial contours become much softer. If you receive filler treatment for sunken cheek areas at Maypure, I am wondering if you can create symmetrical lines that naturally fit my facial proportions without looking artificial. I am worried about potential side effects after the procedure, such as the filler sagging or feeling like hard lumps when touched, like nodules. I would also like to consult about the maintenance period for each product and the approximate dosage I need.
