What Are Smile Lines
Smile lines, also called nasolabial folds, are creases that run from the sides of the nose to the corners of the mouth. They become more visible with repeated facial movements and loss of skin elasticity over time.
Daily Habits That Help Prevent Smile Lines
Protecting skin from sun damage and staying hydrated can slow the development of smile lines. Use broad-spectrum sunscreen daily, wear sunglasses to reduce squinting, and avoid smoking, which accelerates collagen breakdown. A balanced diet rich in antioxidants also supports skin structure.
Skincare and Professional Options
Moisturizers with hyaluronic acid help plump skin and temporarily soften lines. Retinoids, used as directed, can support collagen production over time. For deeper folds, consult a board-certified dermatologist or licensed aesthetician about options like dermal fillers or laser treatments.
