Will Sculptra naturally improve sunken cheeks and facial volume?

As I get older, I can feel my face getting thinner little by little.

My cheeks, which used to be chubby, have become flat, and the area below my cheekbones looks slightly sunken, giving my face an overall long and tired impression.

At first, I considered fillers, but I wanted to find a way to naturally add volume over time rather than the feeling of having something filled into my face.

Then I found out about Sculptra.

It is said to be a method that gradually improves volume by inducing collagen production, but I am curious if there are actually satisfactory changes in sunken areas.

I would like to know if it is particularly effective on areas that have become flat due to fat loss, such as the front or side cheeks.

However, since it is not a procedure that produces immediate results, the fact that it requires multiple sessions is also a concern.

For those of you who experienced it firsthand, how much time did it take to notice the changes?

I would also like to hear if you are satisfied with choosing Sculptra instead of fillers, and what areas should be checked beforehand if you want natural facial volume.
