Biostimulator
An injectable agent that stimulates the body's own collagen and elastin production rather than directly filling or relaxing tissue.
Full Definition
Biostimulatorsare a class of aesthetic injectables — including poly-L-lactic acid (PLLA) and calcium hydroxylapatite (CaHA) — that work by triggering a controlled fibroblast response, prompting the dermis to produce new collagen over weeks to months. Unlike hyaluronic acid fillers, the volumising effect is indirect and gradual. Editors must distinguish the term from 'filler', which implies immediate mechanical volume replacement. The term is increasingly preferred over the older label 'collagen stimulator' in regulatory and brand communications. Correct capitalisation follows generic rather than brand conventions in clinical copy.
Usage
Usage note: Do not use interchangeably with 'filler'. Biostimulatorsare mechanistically distinct and the distinction carries regulatory and medicolegal significance.
In Context
- "The treatment plan specified a biostimulator rather than a volumising filler to achieve gradual tissue regeneration." — Treatment plan document
- "Editors should not substitute 'filler' for 'biostimulator' in patient-facing copy, as the mechanism and expectations differ." — Editorial style guide
