Injection breast enhancement is to inject body fat particles or a liquid colloidal substance into a woman's chest to make the breast plump and feel better. The methods of breast augmentation by injection include autologous granular fat injection breast augmentation and biomaterial injection breast augmentation. Because it involves the plastic surgery of human organs, many people ask whether it is safe. Then, if you want to ensure the safety of breast enhancement by injection, you should pay attention to the following conditions: 1, people who are not psychologically prepared; Inflammation of breast tissue or skin near surgical incision; Suffering from schizophrenia or mental disorder; Patients with immune system or hematopoietic system diseases in important organs such as heart, liver and kidney; Postoperative recurrence or metastasis of breast cancer. 2. Because breast augmentation brings fat at the same time, there must be at least one more wound, so it is very important to keep the wound clean and dry to avoid infection; The dosage of antibiotics can be increased appropriately, and a soft bra should be worn after operation; Follow the doctor's advice, check regularly and take medicine regularly. 3. At present, the safer method is to inject autologous granular adipose tissue. Extract excess fat from the lower abdomen and thighs, purify it into granular fat, and inject it into the back space of the breast to make the breast plump. You can inject about 60 ml each time, and it usually takes 3 months to inject again. Each injection should not be too much, so as to avoid fat liquefaction, necrosis and other complications, resulting in adverse consequences. Experts remind: We must pay attention to the above three points, because it will directly affect the safety of breast enhancement. We should also pay attention to the choice of plastic surgery hospital, which is also an important factor to determine the safety of breast enhancement injection.
