What should you know about deep smile lines?

Nasolabial folds are normal creases between the nose and mouth that become more visible during smiling and talking. With time, collagen and elastic support change, the cheek may descend, and facial volume can shift. Weight change, sun exposure, smoking, and inherited facial structure may also influence their appearance. The fold is not simply a line in the skin: nearby cheek volume, skin laxity, and the movement of the mouth all affect its depth.

Daily sunscreen, moisturiser, and avoiding smoking support the skin, but they cannot recreate lost cheek support. A clinician may discuss Dermal Fillers placed in carefully selected areas, a Collagen Biostimulator Injection, or a Thread Lift when laxity and volume changes are relevant. Each option has different timing, longevity, risks, and suitability. A balanced plan may soften the fold rather than erase natural facial movement, and an examination should include the whole mid-face rather than treating the crease in isolation.

Arrange an assessment if a fold changes rapidly, appears mainly on one side, or comes with facial weakness, numbness, speech difficulty, swelling, pain, or a new lump. Those features need medical attention rather than cosmetic treatment. For gradual, symmetrical folds, a consultation can still clarify whether facial volume loss, skin laxity, or movement is the dominant factor.

Ask what is creating the depth, whether nearby cheek support should be considered, which treatment matches your goals, how results change over time, and what warning symptoms require urgent help.
