Botox injections are noted primarily for the ability to reduce the appearance of facial wrinkles. They’re also used to treat conditions such as neck spasms (cervical dystonia), excessive sweating (hyperhidrosis), an overactive bladder and lazy eye. Botox injections may also help prevent chronic migraines. Botox works by temporarily relaxing facial muscles and easing the muscle tension that causes fine lines and wrinkles. Laugh lines, smile lines, frown lines, and crow’s feet, these fine lines and wrinkles are caused by repetitive facial muscle movements. Smoking, sun damage, and genetics further contribute to these early signs of aging. Over time, these lines become deep creases and wrinkles, prematurely aging your appearance.
