I am considering fillers or Botox because of my deepening nasolabial folds. Will it look very unnatural?

I used to feel upset hearing occasionally that I look stubborn as I get older, but upon closer inspection, I realized it was because the nasolabial folds running from the sides of my nose down to the corners of my mouth had become too deep.

It bothers me because they stand out more whenever I smile, but I'm not sure if lightly filling in these deep wrinkles is the right choice or if I should get Botox.

I'm worried that the area around my mouth might look unnatural or awkward, like it's numb, after the procedure. Could those of you who have experience please share your honest reviews?
