Depot Injection
Pronunciation: DEH-poh in-JEK-shun
A technique in which a concentrated volume of injectable product is placed at a single anatomical point to create a localised reservoir.
Full Definition
A depot injection in aesthetic medicine refers to the deliberate placement of a larger quantity of product — typically a biostimulator, filler, or toxin — at one precise anatomical location, allowing gradual diffusion or sustained local effect. The term is borrowed from pharmacology, where 'depot' formulations release active ingredients slowly from a tissue reservoir. In the aesthetic context, it is most commonly used with collagen-stimulating agents such as poly-L-lactic acid. Editors should distinguish 'depot injection' from the 'bolus technique'; while conceptually similar, 'depot' more often implies a volumetric reservoir with intended diffusion, whereas 'bolus' typically refers to a discrete localised volume of filler.
Usage
Usage note: Borrowed from pharmacology; ensure the clinical context makes the aesthetic meaning clear, particularly in documents with a mixed medical audience.
