What should you know about smooth nasolabial folds?

These folds are normal facial contours, also called smile lines or laugh lines. They become more visible as repeated expression, reduced elasticity, sun exposure and changes in cheek or midface volume alter how the skin drapes. A fold may be present at rest, deepen with smiling, or be accompanied by facial volume loss.

Daily broad-spectrum sunscreen, moisturising and avoiding tanning help limit further photoageing. A dermatologist may assess the cheek, midface and fold together rather than treating the line in isolation. Depending on your anatomy and goals, options can include dermal fillers, collagen biostimulator injection or a thread lift. Each has different timing, aftercare and risks, so treatment should be planned after an examination.

Arrange a clinical assessment if a crease changes quickly, becomes one-sided without an obvious reason, develops a persistent lump, ulceration, bleeding or marked tenderness, or appears with facial weakness or numbness. These features need assessment rather than cosmetic treatment alone.

Ask which part of the face is contributing most to the fold, whether a conservative approach could meet your goal, what material or technique is proposed, how many visits may be needed, and what warning signs require prompt review.
