Hello! Autologous fat filling the face will inevitably lead to bruises, redness and swelling, which will generally disappear with recovery. Seventy-two hours after operation, ice compress first, then hot compress to help reduce swelling. In addition, don't squeeze and touch the surgical site with your hands. After about two or three months, the injection site will be shaped and show a complete effect. The effects of cold compress and hot compress are opposite. Cold compress can slow down local blood circulation, contract blood vessels, relieve pain, stop bleeding and reduce swelling, while hot compress can dilate local blood vessels and relieve pain.
