Dermal filler agents: a practical review

Abstract

Purpose of review: Facial aging results from multiple microscopic (histopathologic) and macroscopic (anatomic) changes. Whereas skin care and traditional surgery have much to offer patients desiring cosmetic improvement, they can fail to adequately address certain signs of facial aging. Soft-tissue augmentation with dermal fillers can successfully address these signs of aging by filling soft-tissue defects caused by age, scar formation, or disease. All dermal fillers aim to achieve the same goal: long-lasting soft-tissue augmentation without side effects. Each dermal filler preparation available for patient use has unique compositions and characteristics that impact its proper handling, therapeutic results, potential complications, and, ultimately, its ideal use. This review surveys the currently available preparations for soft-tissue augmentation.

Recent findings: A review of the medical literature and manufacturers' information are included for dermal fillers currently approved for use by the US Food and Drug Administration. The composition, use, and potential limitation of each available preparation are reviewed.

Summary: Dermal filling agents offer an excellent option for management of certain facial cosmetic changes. Since a wide range of products with significantly different characteristics is available, the treating physician should have sound knowledge of them all.
