How does BOTOX® Cosmetic compare to other products such as collagen and filler materials?
Unlike filler materials, BOTOX® Cosmetic treats the underlying cause of the facial expression lines. Filler materials, such as collagen, only plump up the skin. Although fillers reduce the appearance of lines when there is no facial expression, the moment the person does smile or frown, the lines reappear. Botox® actually prevents the unwanted lines from appearing with facial expression, and often even at rest.
