Are fillers also commonly used for nasolabial folds?

I am inquiring about fillers for nasolabial folds.....

Lately, even when I'm not smiling, I feel like the lines around my mouth are slightly visible, so it bothers me every time I look in the mirror. I don't think they are deep wrinkles yet, but when I wear makeup, that area stands out more, and it makes my face look older.

I’ve heard that nasolabial folds can be significantly improved with fillers, so I’m looking into it. Is it worth getting a consultation even if I’m just starting to worry about them, like in my case? I’ve also seen comments saying that injecting too much can look unnatural, so that’s my biggest concern.

I don't want a drastic change in my face shape; I just want my tired-looking impression to soften a little. I've heard that for nasolabial fold fillers, the condition of the front and side cheeks needs to be considered as well, so I'm wondering if you assess the overall balance of my face during the consultation.

I also want to know if it might feel awkward when smiling after the procedure lol. Anyone please let me know~
