What is Botox® used for?
Botox® is used to eliminate vertical furrows between the eyebrows and on the bridge of the nose, horizontal lines on the forehead, crow’s feet at the corners of the eyes and vertical bands on the neck. Additionally, Botox® is highly effective when used to combat excessive sweating.
Botox® is a non-toxic, highly purified form of Botulinum Toxin Type A, a powerful neurotoxin. Originally used as a treatment for crossed or wandering eyes, Botox® has been approved since 1980 by the American Academy of Neurology, the American Academy of Ophthalmology, and the National Institute of Health. The use of Botox® for cosmetic purposes (since 1990) is an unapproved use of an FDA-cleared drug.
How does Botox® work?
Dynamic facial wrinkles are largely caused by the contraction of small, voluntary muscles involved in laughing, smiling, frowning or lifting the eyebrows. When these small muscles are relaxed, the wrinkles they can cause on the forehead or around the eyes diminish significantly – or even disappear.
Injections of Botox® into the facial muscles weaken or paralyze them by blocking nerve impulses. After Botox®, the treated muscles no longer contract while the overlying skin remains smooth and unwrinkled. The untreated facial muscles continue to contract as before, allowing normal facial expressions.
In its other application as an inhibitor of excessive sweating, Botox® paralyzes the sweat glands of the skin. Treatment sites include underarm skin, or the skin on the palms of hands or soles of feet. It may even be used on the scalp line.
