Dermal Filler
A broad category of injectable substances used to restore volume, smooth contours, and augment soft tissues in the face and body.
Full Definition
Dermal fillers encompass a range of injectable materials approved or used off-label to address facial volume loss, contour deficiencies, and superficial rhytides. Major categories include hyaluronic acid (HA) fillers, calcium hydroxylapatite (CaHA), poly-L-lactic acid (PLLA), polymethylmethacrylate (PMMA), and autologous fat. Unlike botulinum toxin, which acts on musculature, dermal fillers work by physically occupying space within or below the dermis. Editors must note that 'dermal filler' is the superordinate term and should not be used interchangeably with any specific subtype. Regulatory classification of dermal fillers varies by jurisdiction—they are classified as medical devices in many markets, a distinction relevant in regulatory documents.
Usage
Usage note: Use 'dermal filler' as the umbrella category term. When a specific product or material type is known, name it explicitly. Avoid 'filler' alone in formal clinical documents as it is ambiguous.
