Botox is a purified form of a substance called botulinum toxin, type A. It comes from the bacteria that cause botulism. Injections of very small amounts of Botox are used to smooth wrinkles on the face.
Botox is injected into the muscles that cause wrinkles when you frown, squint, laugh or smile. These muscles are in the forehead and around the eyes or neck. The injections stop nerve impulses from moving to the injected muscles, so the muscles relax and the skin looks smoother.
The shots cause very little discomfort, but your healthcare provider may numb the area with ice or an anesthetic cream before giving you the shots. The treatment takes about 10 minutes. The shots do not cause numbness.
It takes 4 days for Botox to start to relax the muscles. The results may last up to 4 months. As the muscle returns to normal, you will see wrinkles again. To keep the effects, you will need to repeat treatments every 3 to 6 months.
Fewer wrinkle lines will appear between your brows ("frown lines") and in other areas where you have the shots. (Deep wrinkle creases may still show.) The process of wrinkling stops as long as the Botox is working.
Before receiving Botox, tell your healthcare provider if you have ever had heart disease or a nerve or muscle disorder such as ALS (Lou Gehrig's disease) or myasthenia gravis. Botox may make these conditions worse.
Do not use Botox if you are pregnant or think you might be pregnant or if you are breast feeding.
Other possible risks include:
Treatment with this medicine may cause your body to form antibodies that may make future treatments less effective. You should receive the lowest effective dose, with at least 3 months between shots.
Injections in the muscles close to the eyes may cause you to blink less. This may harm your eyes. Your healthcare provider may prescribe eyedrops, ointment, soft contact lenses, or an eye patch to protect your eyes until the medicine has worn off enough for you to be able to blink normally again.
This substance is the same as the bacterial nerve toxin that causes botulism. Botulism is a life- threatening illness that makes it hard for a person to move their arms and legs or even to breathe. But the risk of botulism from Botox treatment is low if it is used the right way.
Getting treatment from a qualified physician who is experienced in using Botox may help to decrease risks. Choose a medical setting where sterile techniques and equipment are used.
