What is Botox?
Botox is an injectable formulation with the active ingredient botulinum toxin A, which inhibits nerve signals from reaching muscle tissue in the areas in which it’s injected. This dampens the muscle’s activity, which prevents wrinkles from forming on the overlying skin. Botox has been FDA-approved for many uses, including to stop muscle spasms and even to prevent excessive sweating. It’s most well-known, however, for its ability to reduce wrinkles throughout the face.
