What Is Fat Injection?

The adipose tissue is used successfully and effectively in modern aesthetic and plastic surgery procedures. The adipose tissue taken for injection is also called "adipose graft". The advantages and properties of adipose tissue have led to its widespread use all over the world. Besides being a filler, the adipose cells (adipocytes) are also stem cells. The stem cells aid in tissue regeneration and the survival of the adipose tissue in the area where they are injected. With this feature, the quality of the skin improves around the injection site. Another advantage is the use of one's own adipose tissue, eliminating the risk of allergic reactions.

Facial fat grafting, clinically known as adipose injection, is a modern surgical technique used to restore lost volume and enhance facial contours using the patient's own tissue. This procedure utilizes "adipose grafts," which consist of fat cells (adipocytes) and regenerative stem cells harvested from the patient's own body. The presence of these stem cells is a significant advantage, as they aid in tissue regeneration and survival, while simultaneously improving the quality and moisture of the skin. Because the treatment uses autologous tissue, it provides a healthy and natural-looking result that eliminates the risk of rejection associated with synthetic alternatives. Furthermore, once the initial healing phase is complete, the surviving fat provides a permanent volumising effect that integrates seamlessly with existing facial structures. This dual benefit of volume restoration and skin rejuvenation makes it a highly effective tool in modern aesthetic surgery.

Suitable Candidates and Treatment Areas

‍This procedure is primarily designed for individuals seeking to reverse signs of aging or to fill areas of the body and face where more volume is desired. It is frequently used to fill deep wrinkles, such as the nasolabial grooves, and to add definition to the cheekbones, chin, and temples. Additionally, fat injections are very useful for softening scar tissue on the skin and correcting depressions or collapses. Patients who prefer natural results and wish to avoid the repetitive nature of temporary synthetic fillers are ideal candidates for this long-lasting intervention. The procedure is also suitable for younger patients who may structurally lack volume in certain parts of the face.

Surgical Techniques and Application

‍The process begins with the harvesting of fat tissue from donor areas with sufficient reserves, typically the anterior abdomen or the hip area. Both the extraction and the subsequent injection are performed using very thin cannulas to ensure precision and minimize tissue trauma. For facial applications, specialized methods known as micro-adipose and nano-adipose grafting are often used to process and thin the fat for detailed refinement. Depending on the treatment plan and the volume of fat to be transferred, the procedure can be performed under local anesthesia, sedation, or general anesthesia. Meticulous preparation of the fat graft without air contact is essential to maintain the vitality of the cells before they are injected into the ideal depth of the recipient site.

Expected Results and Persistence

‍The long-term persistence of the results is closely tied to the specialized techniques used during the extraction and preparation of the adipose tissue. While it is generally accepted that approximately half of the delivered fat volume may dissolve within six months to a year, the remaining portion stays permanently in the application area. These results can be repeated or built upon in future sessions if the patient desires further volume enhancement. Beyond the visible volume increase, the skin around the injection site often shows marked improvement in brightness and texture due to the regenerative nature of the stem cells. The final outcome is a more youthful and vibrant facial profile that settles fully as the tissues mature.

Recovery and Postoperative Care

‍The recovery process following facial fat grafting is generally comfortable, with minimal pain reported by most patients. It is expected to experience some redness and swelling for approximately two to three days immediately following the procedure. Bruising may also occur depending on the individual's skin type, though this typically resolves within seven to ten days. Because the incisions used for the cannulas are very small, they do not leave obvious scars and heal discreetly over time. Patients can usually return to their daily routines shortly after the intervention, provided they follow the specific hygiene and care protocols recommended by the surgical team.
