BOTOX

BOTOX is a purified toxin that works by blocking signals from nerves to muscles, leading to the relaxation and weakness of facial muscles that are related to expression lines. The lines, or wrinkles, eventually fade from disuse and new creases are prevented from forming. BOTOX is best used for the treatment of "crow's feet," forehead lines and "frown lines" between the eyebrows. BOTOX can also be used to reduce excessive sweating. The length of efficacy varies depending on treatment location. Early studies indicate that after receiving injections over time, there appears to be a longer lasting effect.
