When treating fine lines and wrinkles, botox is injected into targeted muscles on the face or neck. This temporarily relaxes the targeted muscles, causing fine lines and wrinkles to diminish.

When treating excessive sweating, a dermatologist injects directly into the skin on the underarm.

Botox’s wrinkle-reducing effects lasts about 3 to 4 months — and sometimes longer.

To achieve a natural look, just enough botox is injected to weaken and relax the targeted muscles without affecting other muscles. This allows patients to maintain their natural facial expressions.

No. This treatment does not affect your ability to feel.
