For women who desire subtle breast enhancement, natural breast augmentation, also called analogous fat transfer to the breasts, might be a good treatment plan. With natural breast augmentation, Dr. Krau takes fat cells from an area of the body that typically has an ample amount of fat (e.g., abdomen, hips, thighs), purifies them and injects them into the breasts. The main limitation is that the breasts can only be enhancement by about one cup size, with this technique.
