Facial fat grafting should be chosen by indication, tissue quality and safety—not by promises of permanent volume or “stem-cell rejuvenation.” The procedure transfers the patient’s own fat to carefully selected facial planes, but retention varies and volume alone cannot correct tissue descent.
What problem is being treated?
| Clinical finding | Possible role of fat | Important limitation |
|---|---|---|
| Temple or periorbital hollowing | Small-volume structural microfat | Overcorrection can look heavy; retention varies |
| A-frame or lid–cheek volume loss | Microfat in selected anatomical planes | Does not remove bags or correct every dark circle |
| Descended cheek or jowls | Complement to repositioning | Adding volume does not lift displaced tissue |
| Selected superficial skin concerns | Finely processed nanofat | Does not provide structural volume or replace resurfacing |
Harvesting, processing and placement all matter
Fat is usually harvested from the abdomen or another suitable donor site, processed and placed in small deposits. Dr. June Favarin selects cannula size and anatomical plane according to the recipient area. Periorbital treatment may involve supraperiosteal, subcutaneous or intramuscular placement, but no single plane is correct for every facial region.
Small, distributed deposits favor contact with vascularized tissue. Even with careful technique, part of the graft may be reabsorbed. The retained tissue can change with aging and significant weight variation, including rapid weight loss associated with GLP-1 treatment.
Microfat and nanofat are not interchangeable
Microfat is intended to restore structural volume. Nanofat is mechanically processed into a finer suspension for selected superficial indications; it is not a volumizing filler or a facelift. Evidence does not support guaranteeing regeneration, new collagen or a specific percentage of survival. See the detailed comparison of microfat and nanofat.
Why conservative treatment matters
Intentional overfilling to compensate for possible absorption can distort facial proportions and is especially problematic around the eyelids. Dr. June’s objective is to restore transitions while preserving identity. A later refinement may be safer than excessive volume in one session, but a second procedure is never guaranteed to be necessary or successful.
Previous injectables can change the plan
Hyaluronic-acid filler, biostimulators, PMMA, silicone, threads and energy treatments may alter volume, cause edema or create fibrosis. Product names, dates and treated areas should be documented. When history or examination is uncertain, dermatologic ultrasound may help map material and guide whether surgery should proceed, be staged or be postponed.
Risks and realistic recovery
Swelling, bruising, tenderness and early asymmetry can affect both the face and donor area. Risks include infection, bleeding, prolonged edema, nodules, oil cysts, fat necrosis, contour irregularity, undercorrection, overcorrection and revision. Intravascular injection is uncommon but potentially severe.
Early fullness combines edema with grafted tissue and should not be judged as the final result. Integration and contour evolve over months. Stable weight and medical follow-up are more useful than a promised survival percentage.
Choosing care in Brazil
International patients receive preliminary remote assessment, followed by an in-person examination that confirms the indication and volume. When grafting accompanies blepharoplasty or facelift surgery, the complete operation determines anesthesia, hospital care and recovery. Procedures are performed at Hospital São José when indicated. Belvivere’s concierge support assists with local logistics but does not replace clinical monitoring.
