Juvéderm Collection
Vycross® technology for graduated hardness and volume restoration | Voluma XC, Vollure XC, Volbella XC, Ultra XC, Volux XC
이 치료에 대해
Juvéderm (Allergan/AbbVie, USA) is the global market leader in HA fillers. Vycross® technology optimizes 3D cross-linking between HA molecules. Each product has unique hardness (G' value) and particle size for site-specific use.
[Voluma XC] Highest hardness (G'=44kPa), deep injection for cheeks, marionette lines, jawline. [Vollure XC] Medium (G'=21kPa) for nasolabial fold, dynamic lines. [Volbella XC] Softest (G'=9kPa) for lips, tear troughs, periocular zones. [Ultra XC] Intermediate (G'=15kPa) for nasolabial, superficial. [Volux XC] Ultra-firm (G'=48kPa) for skeletal support—nose, jawline, temples.
작용 기전
Vycross® technology uses advanced manufacturing to create more inter-molecular HA cross-links, achieving higher elasticity and durability vs conventional products. Injected gel provides physical volume filling plus biostimulation via HA degradation products, promoting ASC (adipose stem cell) proliferation. Result: sustained volume effect exceeding actual filler volume.
적응증
기대 효과
Immediate volume effect. Voluma/Volux lasts 12-24 months, Vollure/Ultra 9-18 months, Volbella 9-12 months. Regular touch-ups maintain rejuvenation.
임상 근거
위험 및 부작용
Injection swelling/bruising (1-2 weeks). Juvéderm products have excellent safety profile with multiple FDA/EMA approvals. Rare vascular occlusion with tissue necrosis/blindness risk. Emergency hyaluronidase protocol essential. Very rare granuloma formation.
