Treatment of expression wrinkles.

Botulinum toxin type A works by reversibly inhibiting neuromuscular transmission, which reduces excessive activity of selected facial expression muscles.

Most common treatment areas:

• forehead – horizontal lines,
• glabellar area (“frown lines”),
• lateral eye area (“crow’s feet”),
• bunny lines – transverse nasal lines visible when smiling or squinting,
• smoker’s lines (perioral area),
• downturned mouth corners,
• chin (so-called “orange peel” or “cobblestone” chin).

The goal is wrinkle smoothing while preserving a natural-looking facial expression.
