How about fillers for areas where volume has been lost?

Lately, whenever I look at my face, I’ve been bothered by the fact that it seems to lack a bit of volume compared to before. In particular, when I take photos, my face feels slightly sunken overall, so I started considering fillers. At first, I thought it would be a simple procedure, but the more I researched, the more I heard that the impression can change significantly depending on the area and the amount injected. This made me look into it more carefully than I had anticipated. I heard that getting fillers doesn't necessarily mean the results will be obvious, and that there are ways to naturally add volume with just the right amount. Since there are various types of fillers, I was advised to compare their duration and characteristics, so I am considering getting a consultation first. Above all, I think it is important to clearly communicate the look I want, so I plan to discuss it thoroughly before the procedure.
