Fat Grafting for Facial Rejuvenation Using Stromal Vascular Fraction Gel Injection.

This study used stromal vascular fraction gel (SVF-gel), a mechanically processed fat-derived product, to treat eye bag and tear trough deformity. SVF-gel is prepared by a process of centrifugation and intersyringe shifting and is particularly rich in SVF cells and native adipose extracellular matrix. SVF-gel injection is used alone or combined with transconjunctival eye bag removal. High satisfaction was noted among patients treated with SVF-gel injection for periorbital rejuvenation with fairly low complication rates. SVF-gel injection is a good alternative to assist transconjunctival lower eyelid blepharoplasty and correct the palpebromalar groove, tear trough deformity, and supraorbital hollow.
