21 Neurotoxin Injection for Necklace Lines
Difficulty: ●●
Patient Satisfaction: ●
Risk: ●
Indications
Horizontal lines of the neck are noted at rest and can deepen with aging.
Anatomic Considerations
These lines occur due to the dermal attachments of the superficial musculoaponeurotic system (SMAS). They are seen in the neck from birth but can increase and deepen during the aging process. Treatment of these areas will soften the lines in this area but not completely remove them.
