Botox and similar neuromodulators relax muscles to smooth “dynamic” wrinkles caused by facial expressions—such as frown lines, crow’s feet, and forehead furrows. These injections weaken targeted muscles for three to four months, preventing wrinkles from forming when you smile or frown.
Dermal fillers, on the other hand, add volume or fill lines that are present even when your face is at rest (“static” wrinkles), and can also contour the cheeks, jawline, and lips. Fillers don’t affect muscle movement and typically last longer (six months to several years). Many treatment plans combine both: neuromodulators soften muscle‑driven lines while fillers restore volume and lift.
