Uneven Smile Lines: What to Know

Smile lines, also called nasolabial folds, run from the sides of the nose toward the corners of the mouth. One side may appear deeper because of habitual facial movement, sleeping position, dental or bite differences, or changes in facial volume. Facial Volume Loss can reduce support around a fold, but a visible line does not identify one cause by itself.

A clinician will consider your facial movement at rest and while smiling, skin laxity, volume distribution, and any recent change. Sudden facial asymmetry with weakness or speech trouble is a different concern and needs urgent assessment.

Use daily sun protection and moisturiser to support the skin, but creams cannot replace lost structural support. Avoid repeatedly pressing or massaging the fold in an attempt to level it. If you want correction, an experienced clinician may discuss Dermal Fillers, a Collagen Biostimulator Injection, or Thread Lift after examining facial anatomy, movement, and goals. Each option has different timing, reversibility, and risk considerations.

Book a clinical review if asymmetry appears suddenly, progresses quickly, follows an injury, or comes with numbness, weakness, drooping, difficulty speaking, severe headache, or vision change. For a gradual cosmetic difference, assessment is still useful before an injectable or lifting procedure, especially if dental symptoms or jaw discomfort are present.

Ask what is driving the difference at rest and during smiling; whether volume, movement, or skin laxity is the main factor; which option is reversible; how asymmetry will be managed; and what warning signs should prompt follow-up.
