This technique is unsafe and produces undesirable disfiguring long-term results. The transplanted fat will shrink and harden and may form lumps which are difficult to distinguish from breast cancer. Fat injection of breasts is not performed by any reputable surgeon in New Zealand. It is promoted as a cheap, "natural" method of breast augmentation by untrained "cosmetic surgeons" but the results are unsatisfactory and irreversible.

This procedure is strongly condemned by the New Zealand Foundation for Cosmetic Plastic Surgery.
