Which would be better for deep nasolabial folds, fillers or Botox?

Hello

I am worried because every time I look in the mirror, the deep nasolabial folds around my mouth make me look very tired and older.

Since the lines remain distinct even when I'm not making any facial expressions, foundation tends to settle into them even when I apply makeup. I asked around, and some people say I need to get fillers for my nasolabial folds, while others say I need to get Botox or a lifting procedure along with them for a natural look, so I'm confused.

I'm a bit scared about fillers because I'm worried they might cause indentations or look unnatural. For treating deep nasolabial folds like mine, what procedure is usually the most natural-looking?
