A course of steroid injections is the most common keloid scar treatment therapy in the UK. Steroids prevent cells called fibroblasts from producing collagen, whilst they also weaken the scar and encourage it to flatten. Steroid injections can also reduce any itchiness and tenderness present. Despite the positive outcome of the effects of steroids on keloids, it can be difficult to inject them since these scars are very firm in texture. Also, when injected, progress can be slow, with scars often recurring within five years. Fortunately, absorption in keloids is poor, so only a very small amount of steroid enters systemic circulation. If you and your dermatologist agree on a course of steroid injections, you will visit the clinic a number of times, usually waiting between four to eight weeks between injections.
The mechanical compression dressings are engineered to fit the patient, making it specific to the size and positioning of the scar and to accommodate different pressures depending based on the keloid. This type of dressing is often made of a combination of a stretchy synthetic fabric (known as Spandex fabric), support bandages and zinc oxide adhesive plaster. Compression dressings can also be used along with skin creams and injection therapy for faster results. The dressing will yield the most benefit if worn on a regular basis by the patient.
