botoxDescription: Botox and Xeomin. A naturally occurring polypeptide chain molecule, which blocks the release of chemical mediators from nerve cells, resulting in the failure of nerves to trigger muscle action.

How it's done: Botox is injected into the muscles that cause expression lines (crow's feet, frown lines, worry lines, etc.) to weaken these muscles and the lines they cause. The results last three to four months.

Recovery: In a few days you will notice a refreshed appearance. There is no recovery other than some mild irritation, bruising, swelling or tenderness at the site of injection. Some patients may experience an allergic reaction to the ingredient albumin or transient headaches.

Cost: Varies per unit. Usually $250 and up.
