BOTOX® Cosmetic targets one of the underlying causes of frown lines and crow’s feet—the repeated muscle contractions from frowning and squinting over the years. Your provider will inject these muscles with BOTOX® Cosmetic to temporarily reduce muscle activity. You will begin to notice a visible smoothing of your crow’s feet lines and frown lines between your brows.Wrinkles result from a combination of many factors. It’s not just about cellular changes that can occur over time, reduction of collagen, or damage caused by free radicals in the sun and the environment. When you frown or concentrate, the muscles between your brows contract, causing your skin to furrow and fold. And when you squint, the muscles around your eyes contract and cause crow’s feet.BOTOX® Cosmetic works beneath the skin’s surface and targets the underlying muscle activity that causes frown lines and crow’s feet.
