Botox injections are noted primarily for the ability to reduce the appearance of facial wrinkles. They're also used to treat conditions such as neck spasms (cervical dystonia), excessive sweating (hyperhidrosis), an overactive bladder and lazy eye. Botox injections may also help prevent chronic migraines.
Botox injections block certain chemical signals from nerves, mostly signals that cause muscles to contract. The most common use of these injections is to temporarily relax the facial muscles that cause wrinkles in the forehead and around the eyes. Botox injections are also used to treat conditions that affect how the body functions.
What you can expect?
Before the procedure
Most people don't feel much discomfort during the procedure. But you may want your skin numbed beforehand, especially if your palms or soles are being treated for excessive sweating. Your doctor might use one or more of various methods available to numb the area, such as topical anesthesia, ice and vibration anesthesia, which uses massage to reduce discomfort.
During the procedure
Botox injections are usually performed in a doctor's office. Your doctor uses a thin needle to inject tiny amounts of botulinum toxin into your skin or muscles. The number of injections needed depends on many factors, including the extent of the area being treated.
After the procedure
Do not rub or massage the treated areas for 24 hours. This may help prevent the toxin from spreading to a different area. You can return to your normal activities right after the procedure.
Results
Botox injections usually begin working one to three days after treatment. Depending on the problem being treated, the effect may last three months or longer. To maintain the effect, you'll need regular follow-up injections.
