Cortisone is a chemical produced by the body to counter inflammation. A dilute form of cortisone / kenalog can be injected into acne cysts to help reduce inflammation, pain, and redness. This fast acting treatment is essentially painless and results in fast and effective relief of painful and persistent acne lesions.
Hypertrophic scars and keloids are red, raised scars filled with excessive amounts of collagen. Cortisone injections make these types of scars less noticeable by reducing their redness and inflammation.
