Do you definitely feel the benefits of fillers for nasolabial folds?

I'm upset because the deep nasolabial folds that form every time I smile make me look much older.

I considered a lift as well, but I heard that fillers are the best for immediate results.

If I get fillers injected into the nasolabial folds, is the advantage that they fill in naturally?

Or maybe my biggest worry is that it might look awkward when I make a facial expression.

People around me highly recommended it, saying that just one filler makes your impression look much brighter.

Seeing the people around me has made me really want to get fillers too.

I'm also curious about how long the effects last. I'm a bit of a coward, so I'm a little scared of side effects or it slipping down. I'll be waiting for honest and vivid reviews from those who have actually tried it!
