I'm thinking of getting fillers for the first time. Will it look natural?

Lately, I'm considering getting fillers for my nasolabial folds and volume.
I'm tempted because I heard you see immediate results with fillers, but I'm worried it might look unnatural.
I'm even more worried because I've heard that if fillers are injected incorrectly, it can be noticeable.
Still, I remain interested in fillers because I hear they are a relatively simple procedure.
For those of you getting fillers for the first time, I'm curious about the naturalness and satisfaction level.
