Fillers: Technical Considerations

The arsenal of injectable options available to cosmetic practitioners is expanding rapidly, marked by continuous development of novel products and the broadening of off-label indications for neuromodulators and fillers. Consequently, reconstructive and aesthetic physicians face an increasing challenge in selecting the most suitable products and injection techniques to achieve optimal overall outcomes.

Achieving the best results requires consistency with the patient’s specific anatomy, treatment goals, lifestyle, budget, and psychological context, among other factors. The authors posit that the primary challenge for every cosmetic practitioner lies in precisely determining where and what to inject, considering the diverse facial features and ethnicities in a globalized market.

In this context, we provide a review of Food and Drug Administration (FDA)-approved injectables and discuss how product modification, such as blending with anesthetic agents or other diluents, can offer improved options for delicate or complex anatomic areas. The techniques outlined aim to empower experienced injectors to artfully and safely design customized injectable regimens for their patients.
