Neurotoxins are purified toxins that work 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.
There are four neurotoxins available in our office: Daxxify, Botox, Dysport and Xeomin. They are best used for the treatment of “crow’s feet,” forehead lines and “frown lines” between the eyebrows. Botox and Dysport 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.
