Myobloc™ for Wrinkles
Botulinum toxin can be injected into specific muscles to temporarily relax them resulting in an inability to wrinkle the skin overlying the treated muscle. Botulinum toxin is only helpful for dynamic wrinkles, also known as "wrinkles in motion." It is not as effective on static wrinkles, "wrinkles at rest," but prolonged use of botulinum toxin may help prevent wrinkles in motion from becoming wrinkles at rest.
Botulinum toxin can also be combined with dermal fillers and resurfacing techniques to optimize patient satisfaction. The upper part of the face contains distinct muscle groups that can be selectively paralyzed by a knowledgeable injector. In the lower part of the face, the muscle groups are less distinct making it much more difficult to accurately inject these muscles.
