Drexel Dermatology provides Botox injections to create a more youthful appearance. The most common areas for Botox injections are the frown lines between the eyebrows, the horizontal forehead creases, and crow's feet or laugh lines around the eyes.
What Is Botox?
Botox is a purified protein toxin, produced by the Clostridium botulinum bacteria, that is used to treat "dynamic wrinkles," which are caused by repeated contraction of specific muscles just beneath the skin's surface.
About the Facial Botox Procedure
During Botox procedures, a Drexel dermatologist injects a measured amount of Botox with a very small needle into the muscle creating the wrinkle. Botox blocks the nerve impulse from reaching the muscle and, as a result, the muscle becomes weaker. Botox's intended effect on the muscle develops gradually over seven to ten days, during which the muscle becomes so weak that it allows little to no contraction. The overlying skin then relaxes and the wrinkles eventually soften and often disappear in the treated area.
There is a minor stinging sensation when the Botox is injected, which lasts for a few seconds. The Drexel dermatologist may apply ice to the treatment area for a few minutes immediately before the injections to reduce the discomfort and the amount of swelling. Usually there is no lasting discomfort after the injection. Patients can almost always resume normal activities immediately after the procedure.
The injected muscle will gradually regain normal function over the following months. The muscle recovery time varies among patients. Once the muscle is able to contract again, wrinkles will reappear, requiring the need for repeat injections to maintain results. After several treatments, the effect of Botox may last longer as the muscle becomes weakened.
Side Effects of Facial Botox Injection
After the treatment, there may be slight swelling at the injected spots, which usually goes away within a few hours. Occasionally a small bruise may develop at an injection site. If this occurs, it may take a few days to fade, but makeup can be used to cover the bruise as needed.
The most common side effect is a temporary weakness of muscles near the injection site. When this happens, a patient may develop facial asymmetry or droopiness of the eyelids and/or eyebrows. Muscle function usually returns to normal within a few weeks. In rare instances, a patient may develop resistance to Botox so that additional injections are not effective. If that happens, alternative treatments for the wrinkles should be explored. Very rarely, severe headaches have been reported after Botox injection.
About the Underarm Procedure
Botox injection treatment can control the symptoms of severe underarm sweating when other medicines fail to control embarrassing perspiration. Botox temporarily blocks the chemical signals from the nerves that stimulate the sweat glands. Botox injections temporarily stop the production of excessive sweat in the treated areas only. Sweat will continue to be produced elsewhere on the body.
