The nasolabial folds, commonly known as "smile lines" are the two skin folds that run from each side of the nose to the corners of the mouth.

Volume loss in the middle third of the face leads to lack of support for the lower face and the formation of nasolabial folds. Nasolabial folds contribute to a tired or aged look and are often one of the first things people will identify as a cause of concern in the lower face.

Sometimes treating volume loss in the midface is all that is required to treat the nasolabial fold. Direct treatment of the nasolabial fold is a potentially dangerous treatment and must be performed by a skilled and experienced practitioner. Dr Wassall uses ultrasound in his practice to identify underlying arteries before all nasolabial fold treatments.
