Injectable fillers are safe, predictable, and effective when used by an experienced physician injector for cosmetic enhancement in a properly selected patient.

Physicians must keep abreast of advancements in injection techniques and indications as novel injectable filler products become available. A combination of multiple injectable fillers may be necessary to achieve optimal results.
