SMAS
Pronunciation: ess-mass (initialism)
Also written as: SMAS — Superficial Musculoaponeurotic System
Acronym for superficial musculoaponeurotic system, the fibromuscular facial layer relevant to injection depth and facial anatomy discussions in cosmetic dermatology.
Full Definition
SMAS stands for superficial musculoaponeurotic system, a key anatomical reference point in cosmetic dermatology and aesthetic surgery literature. The acronym appears frequently in articles discussing filler placement, facial anatomy, and rejuvenation techniques. Editors must ensure the full form is spelled out on first use, after which SMAS may be used throughout. It is always written in full capitals with no periods between letters. Confusion with 'platysma' (the neck muscle) is a common editorial error in anatomy-heavy texts.
Usage
Usage note: Always capitalised with no periods. Define in full on first use in any document.
