The primary ingredient in Botox that is responsible for its efficacy is botulinum toxin type A. Human albumin and sodium chloride are included as well, but they have less of an impact.
Botox is a neurotoxic protein that, when injected into muscles, temporarilydisable the ability of the nerve to stimulate muscle contraction. This creates a temporary smooth and relaxed look by reducing wrinkles.
Botox only creates a temporary fix for wrinkles in areas of the face that are frequently contracting. The most common places Botox is injected are between the eyebrows (glabellar lines), forehead, and crow’s feet by the sides of the eyes.
Although Botox is not a permanent solution to wrinkles, it will temporarily stop blocking the nerve impulses. A person will usually need additional injections every 3-6 months in order to maintain desired results.
