I am concerned about deepening nasolabial folds and hollowing of the sides of my cheeks. Who is recommended to receive filler treatment?

As I get older, I often hear that I look tired because my cheeks have thinned and my nasolabial folds look deeply sunken. I am seriously considering a filler procedure, a non-surgical method that can quickly restore volume to these sunken areas.

Since I have absolutely no experience with plastic surgery or minor cosmetic procedures, I am quite worried about whether it will suit my facial type. I would like to know if there are specific recommended filler types or suitable skin conditions for different areas that can achieve natural volume.

Also, I would be very grateful if you could kindly guide me on whether the skin can be refined cleanly to look like my own without feeling too foreign or unnatural, and if there are any types of fillers or procedures you recommend for those who want a natural change in their appearance like me.
