The advantages of autologous fat are that the materials are all your own, which can be taken from other places on your body, and there is no need for incision, the operation is simple, and the recovery period is on the fast side. The disadvantages and risks are as follows: 1. Vascular embolism: in the process of injecting the autologous fat into the cheeks, if you don’t pay attention to pumping it back in the operation, it is possible that the autologous fat will be injected into the small blood vessels. If injected into small blood vessels, the autologous fat will block the blood vessels, and the skin in the blood supply area of the small blood vessels may become dark, and may become black in time, and the patient will feel pain, and in addition, it may lead to skin necrosis, loss of vision, cerebral infarction, and even death; 2, fat liquefaction and calcification: the autologous fat injected into cheeks will not be all viable, and the general survival rate is around 70%, and the fat which has not been viable is likely to undergo Liquefaction. Once liquefaction occurs, the patient will feel pain, the local area may flow pus or fluid, and hard knots may be formed due to fat calcification; 3. Infection: In the process of injecting autologous fat into the cheeks, it is possible that bacteria or viruses will be brought into the subcutaneous tissue. If the infection occurs locally, the patient’s skin may become red, have a swollen and painful feeling, and can be treated with oral antibiotics. If the infection spreads to all parts of the body through the bloodstream, intravenous antibiotics are needed; 4. Requirement to take out the injected cheeks after the change of face shape which is not adaptable; 5. Bilateral asymmetry and uneven skin bumps. In the face of the above risks, it is recommended that beauty seekers go to regular hospitals to avoid the risk of treatment in order to obtain satisfactory results.
