What should you know about laugh lines at 20?

Nasolabial folds run from the sides of the nose toward the corners of the mouth. They can be visible when you smile and remain noticeable at rest because facial structure, inherited features, skin hydration, sun exposure, and changes in cheek fullness differ from person to person. They do not automatically indicate premature ageing. A broader change in [Facial Volume Loss](/symptoms/facial-volume-loss/) is a different concern and needs context.

Photos taken with the same expression and lighting can help you notice whether the fold is stable or changing. A clinician can also check the surrounding skin and facial balance before suggesting any procedure.

Use daily broad-spectrum sun protection, avoid tanning, moisturise if your skin feels dry, and avoid smoking. If the folds bother you, discuss proportional options rather than treating a single crease in isolation. [Dermal Fillers](/treatments/injectables/dermal-fillers/) can add support in selected cases; a [Collagen Biostimulator Injection](/treatments/injectables/biostimulator-injection/) or [Thread Lift](/treatments/aesthetic-procedures/thread-lift/) has different goals, limitations, and risks.

Do not choose a procedure solely from an online image or injectables advertised without a qualified medical assessment. Ask about product choice, placement, expected changes, alternatives, and follow-up.

Arrange a medical review if a fold appears suddenly with facial weakness, swelling, pain, rash, or a marked one-sided change. Seek urgent care for sudden facial drooping, trouble speaking, or weakness elsewhere. Otherwise, treatment is elective and can be considered when the concern is persistent and meaningful to you.

Ask what is creating the fold in your face, whether skin care alone is reasonable, and which procedure would address the contributing structure. Confirm practitioner qualifications, product details, risks near blood vessels, aftercare, and what happens if you dislike the result.
