Autologous Fat Grafting
Patient's own fat for natural volume and firmness restoration
이 치료에 대해
Autologous fat grafting harvests patient's own abdominal fat, centrifuges to purify, then injects into facial hollows and wrinkles. Zero allergies (autologous cells). Engrafted fat cells provide long-term volume; adipose-derived stem cells (ADSCs) included enhance skin quality via regenerative factors. Most natural, long-lasting volumization and rejuvenation.
작용 기전
Harvested fat centrifuged and purified to concentrate viable adipocytes for transplant. Injected via fine needle into facial depressions. 30-50% of grafted fat survives via neovascularization, providing permanent volume. ASCs within fat tissue release growth factors (EGF, PDGF, VEGF, HGF) stimulating surrounding tissue and activating fibroblasts for collagen production. Not just volumization but comprehensive skin regeneration.
