Many wrinkles are caused by repeated contraction of facial muscles, which cause creases in the skin that gradually deepen over time. Botox is injected into these underlying muscles and works by blocking the nerve impulse to the muscle, thereby weakening the muscle. By relaxing the muscles that cause these lines, the creases themselves will soften and can often even disappear.  Botox is especially helpful for those habitual frowners and squinters who often appear stressed when they are actually just concentrating.  Botox can weaken those overactive facial muscles and break the habit of frowning.  Results are dramatic but appear natural, giving you a relaxed appearance that can last for 3-5 months.  There is usually no downtime aside from occasional small areas of bruising from the needle.  Additional information regarding Botox is available at www.botoxcosmetic.com
