Most commonly, anti-wrinkle therapy or Botox (as it is commonly known) refers to local injections of Botulinumtoxin into the muscles that dictate facial expressions. Over time, the repetitive usage of these muscles for activities such as laughing, squinting and frowning can cause the skin to wrinkle and lose its elasticity. Over the last 20 years, anti-wrinkle therapy with Botulinumtoxin has become the treatment of choice for younger patients to prevent the affects of aging and for older patients to re-establish a youthful and refreshed appearance.
