Injectable fillers used today are most commonly made of hyaluronic acid. Common fillers in this category include Juvéderm and Restylane. Fillers are designed to add volume to areas of the face such as the lips, cheeks, or nasolabial folds, improving the appearance of aging and wrinkling.
Neurotoxins are designed to temporarily relax muscles to prevent the formation of lines (rhytids) of the face. Botox and Dysport are the two most commonly used neurotoxins in the United States.
