How much filler is needed to naturally fill in nasolabial folds?

Lately, whenever I look in the mirror, I am very self-conscious because the nasolabial folds around my mouth seem deeper than before. The lines, which used to only be visible when I smiled or spoke, are now slightly visible even when I am still, and when I apply makeup, the base settles into the lines, making them look even more prominent. I do not want my face to look excessively puffy, so I am looking into whether I can improve them naturally with fillers.

I am curious if the required filler volume varies depending on the depth of the nasolabial folds or the condition of the face. I would also like to know how much is typically started for first-time patients and whether the filler settles naturally over time rather than immediately after the procedure. I would also like to consult about the effectiveness and satisfaction levels, the average duration of results, the price, and the total cost.

I am also curious about the duration and level of pain associated with the filler procedure, and I would like to know how long the recovery period is if bruising or swelling occurs. I am wondering if I can go to work or wear makeup the next day if I get the treatment on a weekday, and what precautions I need to take after the procedure. I would like to have a detailed consultation first to see if the volume-filling method is suitable for my nasolabial folds, and then book an appointment to ensure a natural look. Haha.
