BOTOX® is made of a purified Botulinum toxin, and while the idea of injecting a toxin into your face may sound a little daunting, it has actually been approved by the FDA for a wide variety of uses, including migraines, excessive sweating and, of course, anti-aging. BOTOX® is an extremely effective treatment for softening lines between the brow and at edges of the eyes. BOTOX® is injected directed into tiny muscles in the face, blocking the nerve signals that are causing the muscles to contract and your face to wrinkle. As a result, the wrinkles relax and soften.
