Neuromodulators are prescription drugs that, when injected, temporarily paralyze muscles. They contain a purified and safe form of botulinum toxin A, which is produced by the microbe that causes botulism. Neuromodulators are used to treat permanent furrows and deep wrinkles in the skin that are formed by the continual contraction of facial muscles. In addition to their cosmetic applications, they are used to treat a number of medical problems, including excessive sweating, overactive bladder, neck spasms, crossed eyes, chronic back and jaw pain, and migraines.
Applications for Neuromodulators
Although originally approved by the U.S. Food and Drug Administration for the treatment of eye and muscle spasms, neuromodulators were quickly recognized for their cosmetic value. Properly placed injections of neuromodulators block nerve impulses sent to muscles, weakening them to the point where they cannot contract, and temporarily eliminating moderately severe furrows and lines. Neuromodulators are used to treat the following:
- Forehead furrows
- Frown lines
- Crow's feet
- Skin bands on the neck
Neuromodulator Procedure and Results
Using a very fine needle, neuromodulators are injected directly into facial muscles that are causing furrows and lines. Receiving the injections requires no anesthetic, but some doctors choose to numb the area to be injected with ice packs or a topical anesthetic cream. Results can usually be seen within a few days of treatment, and typically last up to four months, although areas that are treated on a regular basis may retain results longer. Injections should be given only by qualified medical professionals.
Side Effects of Neuromodulators
Injection-site side effects of neuromodulators are usually mild and temporary, and include the following:
- Pain
- Infection
- Inflammation
- Tenderness
- Swelling
- Redness
- Bleeding
- Bruising
Normal activities may be resumed immediately after receiving injections.
