Facial Danger Zone
An anatomically defined region of the face where injection of dermal fillers or other injectables carries significantly elevated risk of vascular occlusion or nerve injury.
Full Definition
Facial danger zones are specific anatomical areas where major vessels or nerves lie in predictable but vulnerable superficial positions, making inadvertent intravascular injection a serious risk during aesthetic procedures. Key danger zones include the glabellar region (supratrochlear artery), the nasal tip and alar base (angular and lateral nasal arteries), the temporal region (superficial temporal artery), and the nasolabial fold area (facial artery). Editors must ensure the term is consistently capitalised or lowercased per the publication's style guide; some journals use capitalised 'Facial Danger Zone' when referencing a named anatomical framework. The concept underpins safety guidance sections in injection technique articles and must not be edited away as lay language. It is distinct from the broader concept of high-risk anatomical zones, which may include non-facial body areas.
Usage
Usage note: Capitalisation varies by publication; editors should apply the house style consistently. Do not edit out as jargon — it is a recognised anatomical safety term in aesthetic medicine.
