Facial lines are caused by a combination of factors, including cellular changes that may occur, reduction of collagen, or damage caused by free radicals from the sun and the environment. Repeated muscle contractions from frowning, squinting, or raising eyebrows cause skin to furrow and fold, gradually resulting in the formation of facial lines. BOTOX® Cosmetic works beneath the surface and temporarily reduces the underlying muscle activity that causes moderate to severe frown lines, crow’s feet and forehead lines in adults – to help them look visibly smoother.
