Botulinum Toxin
Pronunciation: bot-yoo-LY-num TOK-sin
A neurotoxic protein derived from Clostridium botulinum, used in aesthetic dermatology to temporarily paralyse facial muscles and reduce the appearance of dynamic wrinkles.
Full Definition
Botulinum toxin is a neurotoxic protein produced by the bacterium Clostridium botulinum that blocks acetylcholine release at the neuromuscular junction, causing temporary muscle relaxation. In aesthetic dermatology, it is most commonly administered via injection to soften dynamic wrinkles such as frown lines, crow's feet, and forehead lines. It is available in several formulations including onabotulinumtoxinA, abobotulinumtoxinA, and incobotulinumtoxinA, each with differing unit equivalences. Editors must be alert to the correct generic and brand name distinctions and should not use the colloquial shorthand 'Botox' as a generic term in clinical or regulatory documents. Dosing is measured in units, and unit values are not interchangeable across formulations.
Usage
Usage note: Do not use 'Botox' as a generic term in clinical writing; Botox is a registered trademark of Allergan. Always specify the formulation and unit dosage. 'Botulism toxin' is incorrect and should be flagged.
