Nasolabial Fold When Smiling

Smiling lifts and gathers the cheek while the muscles around the mouth move. This naturally creates a line between the nose and mouth, even in younger skin. With time, reduced elasticity or facial volume changes can make the line linger after the smile relaxes.

Compare the area at rest and during expression in similar lighting. A fold that is symmetric and changes with movement is generally approached as a facial-structure or cosmetic concern, not judged from the crease alone.

Start with daily sun protection, moisturiser and gentle cleansing to support the skin barrier. If the line remains bothersome, a qualified clinician can assess whether cheek support, skin laxity or texture is contributing. Options may include dermal fillers, collagen biostimulator injections or a thread lift, depending on anatomy and goals.

Bring photographs showing your natural expression and relaxed face. Discuss whether preserving movement matters to you, how much softening is realistic, and what recovery and follow-up involve.

Book medical assessment if the change is sudden, strongly one-sided, painful, swollen, associated with numbness or facial weakness, or accompanied by a new lump or persistent sore. Sudden weakness of the face or trouble speaking requires urgent care. A long-standing smile-related crease can be reviewed routinely.

Is my fold present only with movement or also at rest? Which nearby structure affects it most? How can treatment preserve a natural smile? What are the alternatives and expected recovery?
