I've heard a lot of people say that getting fillers makes your face look younger. Is the difference actually significant?

Hi haha. Lately, whenever I look in the mirror, I've been quite worried because my face seems a bit more tired than before. My skin condition isn't bad, but for some reason, I feel like it lacks vitality. So, while looking into various options, I became interested in fillers.

I've seen so many reviews saying that just one filler treatment makes the face look much younger, so I'm curious if there is actually that much of a difference. In particular, I've heard that even a slight increase in volume can drastically change one's overall impression.

I don't want to change my face shape itself; I just want to improve the sunken look a little. I think I would be satisfied if it just brought back a natural vitality, so I'm curious if that kind of result is actually possible.

For those of you who have received fillers, what was the most satisfying change after the procedure? While your own satisfaction is important, I am also curious if you heard comments from those around you saying your face looked better.

I would also like to know if there is a possibility that the shape of the filler might change or become uneven over time. Since this is my first time getting it, I have a lot of unnecessary concerns.

It would be a huge help if those with experience could share their satisfaction, duration of results, and recommended areas. We look forward to hearing various reviews.
