Skin Growth Injection
PDLLA microspheres for long-term fibroblast stimulation
About This Treatment
Skin growth injection (Juvederm Voluma, Sculptra) uses PDLLA (poly-lactic acid) microspheres. Limited direct volume augmentation; instead, gradual PDLLA absorption signals fibroblasts to rebuild. Over 6-12 months, endogenous collagen production accelerates, skin becomes thicker and firmer. Ultimate "growth-promoting" anti-aging treatment.
Mechanism of Action
PDLLA microspheres (40-63μm) trigger granulation tissue formation; macrophages gradually absorb microspheres over 12-24 months. During absorption, fibroblasts chronically stimulated for sustained type I collagen production. Marked improvement at 6 months, peak at 12 months. Endogenous collagen persists after absorption; effects long-lasting.
Indications
Expected Results
30% facial volume restoration at 6 months. Marked nasolabial fold and marionette line improvement by 12 months. Effects last 2-3 years. More natural than traditional volumizers; simultaneous skin quality improvement.
Clinical Evidence
Risks & Side Effects
Transient injection-site redness/swelling (1-2 days), minor bruising. Rare granuloma formation (typically resolves 2-3 weeks). Foreign body sensation rare (PDLLA bioabsorbable).
