A facial fat transfer is different from dermal fillers in a few ways. First, the process of a fat transfer involves harvesting and purifying fat cells from another area of your body, usually the abdomen or thighs. The harvested fat cells are then injected into the areas where you want to add volume. This technique has been used for decades with great success, as the cells are natural and biocompatible. On the other hand, dermal fillers involve injecting a synthetic substance, such as hyaluronic acid or collagen, into the skin to add volume and reduce wrinkles. Dermal fillers can produce similar results to fat transfers; however, they do not last as long and may not produce the same natural-looking results. Additionally, dermal fillers can cause allergic reactions or other side effects in some patients. Fat transfers offer a more permanent solution than dermal fillers since the fat cells are your own and will stay in place for an extended period of time.
