Many patients are confused about the difference between a neurotoxin such as Botox or Dysport and fillers. The former works by temporarily freezing the underlying dynamic muscle in the treatment area which smooths out the surface skin. A filler, on the other hand, actually fills in an area that has lost volume. Typically, I use both for a non-surgical facial rejuvenation procedure as they really complement each other. The combination of a filler or fillers with a neurotoxin is a great way to address facial aging.
