If you have the tendency to develop keloids, then you need to be extra careful even before undergoing a surgery, especially when opting for elective surgeries like face lifting.
Pamper your skin with regular skin and spa treatments and ensure that it remains sufficiently moist. This will relax tension around your operated skin and muscles, reducing the chances of forming a keloid.
Steroids are also successful for treating Keloid scars and are effective in reducing post surgery itching, burning and swelling.
Compression garments can also be effective. These include stockings, socks and sleeves which help flatten the scars somewhat and reduce swelling as well.
In severe cases, surgeons usually do skin grafts, but it is a risky procedure since you can develop more keloids as a result of that surgery.
