Can upper lip fillers reduce the appearance of nasolabial folds?

I've had varying success with fillers injected directly to nasolabial folds. Sometimes I feel the filler has actually exacerbated the folds. Is there a way to place filler above the upper lip that will also reduce the NL folds? I think my facial anatomy might not be appropriate for NL fillers and I'd prefer a lower risk ( though potentially lower reward) way of managing them. Thanks!
