Deflation and descent of malar fat cause folds between the nose and mouth.
Nasolabial folds are sometimes referred to as smile or laugh lines. The fold runs from the edge of the nose to the mouth. As a person ages, the fold becomes more pronounced.
Some people do not like the way it looks while others feel it is a natural and welcome part of aging.
Apart from age, smoking and chronic sun exposure are other risk factors for their development.
Dermal fillers such as Restylane® or Juvéderm® can be used to treat these folds.
