The duration of facial fat filler maintenance depends on various aspects, usually 3-5 years, but it varies from person to person. Facial lipofilling is the process of implanting fat from other parts of the body into the face to achieve a rejuvenated look. Facial lipofilling does not work in one session and needs to be repeated 2-3 times. Multiple fillings allow the fat cells to be better absorbed by the skin and thus survive permanently. In most cases, patients can last 3-5 years after having facial fat implants, but the survival rate after transplantation varies greatly as each patient’s skin absorption capacity is different. It is important to note that patients will experience a swelling period of about 1 month after facial fat filler, and the swelling will usually be completely reduced in about 3 months. Therefore, patients are reminded to apply cold compresses in a timely manner and take care to avoid facial infections to prevent scarring.
