Injectable fillers such as Restylane, Perlane and Juvederm can be used to treat smile lines (nasolabial folds), the "parenthesis" shaped reach from the side of the nose to the outer corners of the mouth. While it is usually difficult to eliminate smile lines completely, facial fillers can be used to dramatically soften these lines and make them less noticeable.

These photos show a typical improvement in the appearance of smile lines after injection with a facial filler such as Restylane, Perlane or Juvederm. Again, it is difficult to eliminate smile lines completely, but they appear much softer after treatment.
