Review Comparative Study
Comparative physical properties of hyaluronic acid dermal fillers.
Hyaluronic acid (HA) fillers are becoming the material of choice for use in cosmetic soft tissue and dermal correction.

A careful review of these gel characteristics is essential in determining filler selection, performance, and patient expectations.
