Botulinum toxin therapy
The injection of botulinum toxin, commonly known as Botox, has become very popular for reducing wrinkles and rejuvenating the aging face. The effects are only temporary, but the injections can be done quickly, require no recovery time, and are not as complicated as many other cosmetic procedures for the face.
Botulinum toxin is produced by Clostridium botulinum bacteria. When a small amount of Botox is injected into a muscle, it blocks nerve signals that tell your muscles to contract. The effects of this are that it temporarily weakens or paralyses the facial muscles and smoothens or eliminates wrinkles in the skin for a few months.
How well it works
Within 72 hours after treatment, the injection of Botox partly or completely smoothes wrinkles for most people. But the results are temporary, typically lasting between 3-4 months. You will have to return for injections every 3-4 months to maintain the effects. The dose of Botox usually is the same each time you get an injection.
The most common side effects are:
Drooping eyelid that may last a short time.
Botulinum toxin is injected directly into the target muscle to treat vertical lines between the eyebrows and on the bridge of the nose, the squint lines or cow’s feet at the corners of the eyes the forehead horizontal lines and platysmal muscle bands often visible on the neck, commonly known as turkey neck. It may also be used for eyebrow positioning. Once the muscle is weakened and relaxed, it cannot contract. Since there is no way to make the undesirable facial expression, the lines gradually smooth out from disuse, and new creases are prevented from forming. Other muscles like those needed to raise the eyebrows are not affected so a natural expression is maintained. Botulinum toxin may not be as effective on the smile lines around the mouth because the muscle action in this area in needed for expression and important functions like eating.
