The nasolabial fold is he deep crease running from either side of the nose to the corners of the mouth. This fold is created by repeated movement of the mouth and generally becomes more noticeable with age.

While it is natural to have slight fold here, a deep fold can be unattractive and make you look older than you truly are. Treatment with dermal filler in this area can soften the folds, resulting in a more youthful appearance.
