Botox®
Botox® is a purified form of the botulinum toxin that is obtained from bacteria. It works by blocking nerve signals in the muscles where it is injected. When those nerve signals are interrupted, the affected muscle is temporarily paralyzed or frozen. Without movement of these selected muscles in the face, certain wrinkles may be softened, reduced, or even removed.
For wrinkle treatment, Botox® is primarily used to treat dynamic wrinkles, or, in other words, wrinkles caused by muscle movement. These wrinkles occur naturally around the eyes and mouth, as well as in between your eyebrows. They become more pronounced with age. Botox® injections relax the muscles near these wrinkles. Not allowing the muscles to move reduces the appearance of dynamic wrinkles. Botox® is not used for fine lines caused by collagen breakdown.
