Inquiry regarding satisfaction and duration of nasolabial fold fillers

Hello. I am a man in my 50s concerned about deepening nasolabial folds. As I get older, the wrinkles make my impression look somewhat dull and aged, so I am considering filler treatment.

I saw online that people in their 50s need to consider skin sagging as well, so I am genuinely curious about the satisfaction level of those who have actually received filler injections in the nasolabial fold area. Does it make your expression look awkward when you smile?

Also, I would appreciate your advice regarding the actual difference in duration between domestic and imported fillers, and whether it is better to get fillers alone or to combine them with other procedures like lifting for my age.
