Smile Lines Around the Mouth: What to Know

Nasolabial folds extend from the side of the nose toward the corner of the mouth. Everyone has some underlying fold because it reflects the way cheek tissues meet the upper lip. Smiling and talking make it more visible, while reduced skin elasticity, sun exposure and facial volume changes can deepen its shadow. A fold can be present without a medical problem. A clinician considers the whole face, skin quality, symmetry and movement rather than treating the line in isolation.

Daily sunscreen, shade, gentle cleansing and moisturising support the surrounding skin, but they cannot change facial anatomy. If the fold bothers you, a qualified practitioner may discuss dermal fillers, collagen biostimulator injections or a thread lift. Fillers can restore selected volume; biostimulators encourage gradual collagen response; a thread lift uses placed threads to create a lifting effect. Each has distinct risks, recovery and limits, and the safest plan depends on anatomy and medical history.

Have a new or one-sided facial change examined if it appears suddenly, progresses quickly, causes weakness or numbness, or comes with swelling, pain, a persistent sore or a changing skin mark. Before an aesthetic procedure, mention allergies, medicines that affect bleeding, autoimmune conditions, pregnancy or breastfeeding, previous filler or threads, and any active infection. Urgent review is needed after treatment for severe pain, unusual skin colour, vision changes or facial weakness.

Ask what is contributing most to the fold, whether volume restoration or skin stimulation is appropriate, who will perform the procedure, what recovery involves, and how complications would be managed.
