Which procedure looks more natural, Sculptra or Juvelook Volume?

Lately, as I've lost weight in my face, my front and side cheeks look sunken compared to before, so I'm considering getting a procedure. As I get older, I'm really concerned that my face is losing elasticity and volume overall.

At first, I considered fillers, but I hesitated because I was worried they might make my face look too puffy or look obviously fake. Then I learned about Sculptra and Juvelook Volume, and I heard that since both work by inducing collagen production, they can provide natural-looking improvement.

What I'm curious about is the actual difference between the two procedures. I want to know the differences in the degree of facial volume gain and skin elasticity improvement, as well as which one offers more satisfactory results in terms of duration.

In particular, since I don't have much fat on my face and tend to have sunken cheeks, I want an overall soft and natural impression rather than having my face filled out excessively.
