Fat Grafting and the Case Against Fillers

Fat grafting differs from filler in one respect that determines most of the others: the material is the patient’s own tissue rather than a manufactured product. That affects allergic risk, how the result behaves over time, and what a treatment consumes.

What fat grafting involves

Fat grafting, also known as fat injection, transfers fat from one area of the body to another to add volume and alter contour. It is used to restore volume where it has been lost.

Fat is harvested by liposuction from a donor site such as the abdomen, thighs or hips. It is then purified to remove excess fluid and non-viable cells, so that only viable fat cells are used. The purified fat is injected into the target area in small parcels.

The process begins with a consultation, at which the areas to be treated and suitable donor sites are identified. During the procedure a small incision is made to extract fat using a cannula.

Because the graft is the patient’s own tissue, the risk of allergic reaction associated with a foreign material does not apply. Recovery time varies with the area treated and the volume transferred, but is generally limited. Swelling and bruising are expected and typically settle within a week or two.

Autologous tissue rather than a product

Using the patient’s own tissue means there is no manufactured filler being introduced, and no question of compatibility with a foreign substance.

The result also behaves differently over time. Synthetic fillers require repeat treatment on a defined cycle. Fat that establishes a blood supply integrates with the surrounding tissue and persists, which means fewer repeat interventions.

There is a second consequence: the harvest itself contours the donor site. The liposuction that supplies the graft reduces volume where it is not wanted while adding it where it is.

The texture is also different. Grafted fat integrates with the surrounding facial tissue and behaves as tissue rather than as a gel deposit.

Fewer repeat treatments

A treatment that requires repeating every six to twelve months consumes a manufactured product, its packaging and a clinical appointment each time. A procedure that produces a durable result does not.

This is a practical argument as much as an environmental one — it reduces the frequency of intervention.

Safety considerations

Fat grafting is a surgical procedure and is assessed as one.

Candidates should be in good general health. Medical conditions, allergies and current medication are discussed at consultation and the plan adjusted accordingly.

Because the graft is autologous, allergic reaction and rejection are not the principal concerns. The relevant risks are infection, uneven distribution and excessive resorption of the graft.

Post-procedure care matters to the result. Following instructions on managing swelling and bruising, and avoiding strenuous activity in the early period, supports graft survival. Swelling and temporary numbness are expected. More significant complications are uncommon but are set out before the procedure.

Who it suits

Fat grafting suits patients who have adequate donor fat, reasonable skin quality in the area being treated, and who want a durable rather than a repeatable result. Patients who are very lean may not have sufficient donor tissue.

How we quote

Fees depend on the areas treated and the operating time required, and are set out in writing after consultation.
