I am looking into filler treatments, so I would appreciate your advice.

Every time I look in the mirror, because of the deep nasolabial folds extending from the side of my nose to the corners of my mouth

You look very tired and old.

I try home care in my own way, but,

Perhaps because the wrinkles were already there, it didn't have much effect, so I eventually started considering filler treatment.

Since it is my first time, there are many things I am worried about.

After getting fillers, do you notice unnatural muscle movements when smiling or a strong foreign body sensation?

And I am curious about how long the maintenance usually lasts.

I am also worried about whether there will be any side effects if the sagging recurs after the procedure.

I would be very grateful if you could share any valuable information regarding the procedure!
