Hello, my friend, the most common side effect of autologous fat-rich chin after this operation is redness and swelling, which mostly disappears about a week after this plastic surgery. After operation, the operator must try to avoid sun exposure and pay attention to clean skin. The postoperative period is red and swollen. Symptoms of redness and swelling occur regularly in the treatment area, with an interval of 2 weeks or once a month. Some patients can get better after antibiotic treatment; There are also patients who are ineffective in treatment, but can naturally subside after the cycle, and relapse again when the cycle attacks.
