Facial lines or wrinkles can be classified into two types, those resulting from sun damage and the natural aging process of the skin, and those wrinkles produced by lifelong contraction of facial muscles, also called muscular lines. Muscular lines disappear when the muscle that produces them is inactivated or weakened by a muscular blocking agent like Botulinum toxin - which typically occurs a few days following the procedure. By eliminating the excessive muscular pull, the surface of the skin stretches out and the wrinkle disappears
Of the many uses of Botulinum toxin the cosmetic uses include treating the vertical lines between the eyebrows and on the bridge of the nose, squint lines or crow´s feet at the corners of the eyes, forehead horizontal lines, the line around the mouth, thinning of the jaw muscle in people with square faces and the muscle bands often visible on the neck, commonly known as "turkey neck." It is also used in the treatment of ‘Hyperhydrosis’ which is excessive sweating under the arms. Those who suffer from this knows only to well the discomfort it causes.
The procedure only takes a few minutes during which small doses of Botulinum toxin are injected into selected muscles. The toxin binds to the nerve endings and in doing so blocks the release of the chemical signaling agent acetylcholine, which would otherwise trigger the muscle to contract.
After injection, the muscle relaxes, creating a smooth surface that lasts about three to four months before the muscle fully recovers its original strength. Even after the actual effects of Botulinum toxin are gone, the lines that are left behind are not as deep and don´t return to their original severity.
