This is a very common treatment for keloids; it is also very effective. Corticosteroid injections are steroid injections used to treat keloids through shrinking. We give them every four to eight weeks to help flatten the keloids. With the first injection, you will notice a relief in symptoms and the keloid will become softer. After several injections, it reduces in size making is almost as flat as the skin surrounding it. We combine steroid injections with other treatments to reduce the chances of them growing back after 5 years.
