Why Do Nasolabial Folds Cause Facial Volume Loss?

Nasolabial folds are the lines running from each side of the nose toward the corners of the mouth. The fold itself is shaped by facial expression, the attachment of skin to deeper tissues, and the way cheek tissue rests over the upper jaw. With time, skin may lose some elasticity and fat compartments in the cheek may become smaller or move lower. Bone and connective-tissue support can also change. These combined shifts create a transition between the cheek and the fold, so the crease may appear stronger even when the skin surface has not changed dramatically.

This pattern is usually gradual and often differs between the two sides of the face. Sun exposure, smoking, weight changes and natural facial structure can influence how visible it becomes. Facial volume loss can occur for reasons unrelated to nasolabial folds, so an examination is needed before choosing a treatment.

Take clear photographs in relaxed facial expressions and note whether the change developed gradually or followed weight loss, illness or a procedure. Daily broad-spectrum sunscreen, avoiding smoking and using a gentle moisturiser can support the skin, although these steps do not restore lost deeper volume. A dermatologist or qualified aesthetic clinician can assess cheek support, skin laxity, movement and dental or bite-related factors. Options may include observation, skin-focused care or carefully selected volume-restoring procedures; the suitable choice depends on your anatomy, goals and medical history.

Arrange a clinical assessment if the change is sudden, strongly one-sided, painful, associated with weakness or numbness, or follows an injury or injection. Seek prompt care for facial swelling with breathing difficulty, spreading redness or fever. For a gradual cosmetic change, a routine appointment is appropriate, especially if the fold is changing quickly or affecting eating, speech or confidence.

Ask what is contributing most to the fold: cheek volume, skin laxity, facial movement or another cause. You can also ask which options match your anatomy, what temporary effects to expect, how results will be reviewed and what warning signs should prompt contact after treatment.
