My nasolabial folds seem to be getting deeper, so I am considering a filler consultation.

Lately, the part of my face that bothers me the most is my nasolabial folds. In the past, they were only slightly visible when I smiled, but lately, I'm worried because lines seem to be visible on both sides even when I'm not making any facial expressions. They seem to look even deeper, especially on days when I'm tired or my skin is dry, so it feels like they aren't covered up even with makeup.

I learned about fillers while looking for various solutions for my nasolabial folds. However, since it involves injecting directly into the face, I have many concerns before making a decision. I do not want my face to look chubby from excessive volume; I simply want the sunken areas around my nasolabial folds to be naturally filled in.

I have heard that even for nasolabial folds, the approach can vary depending on whether they are caused simply by a lack of volume or by skin sagging. In that case, during the consultation, would it be better to ask them to check for overall facial sagging and volume as well, rather than simply stating that I want to get rid of the nasolabial folds?

I am curious whether changes are visible immediately after a filler procedure, or if the final shape can only be determined after some time due to swelling right after the treatment. I would also like to know if there is a possibility of bruising or swelling, and how long the recovery period is. I would also like to know if it is advisable to allow a few days of buffer time if I have an important schedule.

If anyone has consulted or received filler treatments for nasolabial folds, I am curious to know how naturally the results actually turned out. I would also appreciate it if you could share the essential points to check during the initial consultation and how to explain the desired outcome.
