I'm curious about the characteristics and treatment cycle of fillers.

Lately, when I look in the mirror, my face seems to look flat overall, so I am looking into fillers.

I would like to naturally improve areas that appear to lack volume, such as nasolabial folds or the cheeks, and I am curious about the characteristics of fillers.

I would like to make subtle adjustments that suit my face rather than making too obvious changes, so I would like to know if this is okay.

I am also curious about how the filler treatment cycle is usually determined, and whether the effects last indefinitely after just one session.

I would also like to know if the duration or method of maintenance varies depending on the area.

Since this is my first time getting fillers, I'm unsure which area to choose, so I'd like to hear about the satisfaction levels and reviews from those who have actually had the treatment.
