The nasolabial fold, originating at the corner of the nose and extending diagonally toward the corner of the mouth, undergoes changes with the aging process. As time progresses, this fold deepens, casting a shadow that can impart a tired appearance to the face. Dermal fillers present an effective solution to address nasolabial folds by smoothing the crease and diminishing the associated shadow.

By using dermal filler to the nasolabial lines, volume can be added/restored to these folds, which helps to flatten out the deep shadow-causing creases.
