What is the difference between anti-wrinkle and filler?

Injections with anti-wrinkle are used to temporarily relax muscles that are pulling the skin in a way that causes wrinkles. Generally, but are not limited to, these injections are in the upper third of the face, including the forehead, frown and crows feet.

Dermal fillers can also be used to improve the appearance of wrinkles, however their primary purpose is to restore volume where it has been lost in the face due to ageing effects such as movement of underlying tissues and bone resorption. Generally, but not exclusively, fillers are used in the lower two thirds of the face in areas such as the cheeks, chin, lips and nasolabial folds.
