Which area is most commonly treated when getting fillers for the first time?

I've become interested in fillers, so I'm looking up various things.

But there were actually a lot more parts than I expected.

I was confused because there are so many different types, such as nasolabial folds, cheekbones, chin, and lips.

I'm curious where people usually get it done the most for the first time.

I wonder if there is a specific part that is particularly satisfying?

I've also seen comments saying that once you start, you want to work on other parts of your body too.

I'm wondering which area would be suitable if I want to make a natural change.

I'd like to know a little bit before getting a consultation.

I'd appreciate your opinions if you have experience.
