Fillers are injectable medications that are used to restore volume loss in areas of the body, frequently used in facial procedures. Fillers are made from synthetically produced hyaluronic acids (HA) that mimic natural hyaluronic acids found in most living cells.
Hyaluronic acid is a naturally occurring sugar that the body uses as one of the building blocks for cells. When not used as a building material for cells, HA binds to water and creates a gelatin-like substance that is perfect. There have been thousands of studies and clinical trials using hyaluronic acids over the past 70 years.
