How long did it take for the swelling to go down after getting nasolabial fold fillers?

It's the day after getting nasolabial fold fillers, and it's still really swollen.

My nose bridge filler wasn't this bad; I wonder if my nasolabial folds are particularly swollen.

I'm not sure if it's supposed to last this long.

Does the degree of swelling vary depending on the area?

For those of you who have had it, how long did it take for the swelling to go down?
